Car part tuning is still more or less in GT Sport its just not as fancy to look at.
This really comes down to your playstyle of Gran Turismo games.
Are you a player who enjoyed making full use of past tuning options?
If you answered yes, then the lack of Turbo kits/Superchargers, Ballasts adjustments, different types of transmissions, wing shop, Chassis Rigity Improvements, drivetrain improvements, ect takes away a lot replayability in GT Sport for many players.
If you answered no, then your rebuttal of
"Car part tuning is still more or less in GT Sport its just not as fancy to look at" makes perfect sense, and I understand why you would feel that way. You aren't going to notice something that's gone, when its something you never made use of.
GT Auto Car Care was a nice gimmick but that was literally all it was. Wash my car, oil change lol...
I definitely agree that's how it felt in its first iterations, but I liked the way GT Auto's purpose progressed into the PS3 era. By requiring you to rebuild the engine of cars with high mileage from the Used Car Dealership, if you wanted the full amount of power that the car would have new. If you are going to buy a cheap car with very high mileage on the cheap, it makes sense the car would have some issues. It makes sense that you would need to pay money to restore the engine, and get the most power possible. If want to save money, you can also just use the car in its depleted form, and sell it afterwards. Just sounds like game balancing to me. Also, I agree Car Washes are silly, but they could easily add some life to the silly feature if the car progressively got dirtier the more you ran off track in future games... Almost like the game would be telling you indirectly 'you suck at driving'.
Let's not act like Gran Turismo Sport doesn't have its own fair share of gimmicks too. I remember one of Kazunori's strategies for promoting GT Sport was telling players they would get an 'FIA Digital License' while competing in Sport mode. I don't even think that even came to be, because it was so silly.
Like I said earlier a lot of the single player portion and Championship racing has been moved over to the 'Sport Mode'. This is where you can find stuff like the Single player Manufacturer events etc.
The Manufacturer Cup races you are referring to currently aren't in the game because the FIA Championship season is over, and the date when the next season will begin isn't even revealed yet.
Also, this isn't what I was referring to anyway. The 'Manufacturer Events' in GT4 were events listed in the manufacturers Brand Page. These events were championships that only allowed certain models of the hosting brand, to compete against one another in a Championship. These races were some of the best rewarding events in the early portion of the game. It gave you a reason to try different cars, and it was a nice feature. For example, Subaru's 'Stars of Pleiades' awarded over Cr. 75,000 for winning the championship in a Subaru which could be bought cheaply in the Used Car Dealership.
On the topic of GT Sports Manufacturer Cup: The only other thing to do in Sport mode when the season is over, is play the A,B,and C daily races provided to players, over and over on repeat till the list is refreshed once a week. That is in no way a suitable replacement to the elaborate, diverse, and expansive GT Mode of Gran Turismo 4.
Again as mentioned previously, GT Sport is more Sport & Race car orientated. Therefore it makes sense to not have to compromise on budget tyres or brakes? You wouldn't put something from Halfords onto a Lambo would you?
Maybe it doesn't belong in Sport mode, for competition balancing sake. But in the rest of the game, you shouldn't have the ability to add Racing Super Softs to your Aston Martin DB11 as soon as you buy it. It makes all the other 12 tires choices in the game, completely worthless. It just doesn't make sense from a game balancing or the realism prospective that you used.
City courses you have a point but maybe they were dropped because a lot of those courses were extremely tight, awkward and not designed for sports car racing? Especially if you like to get through cleanly.
Have you ever heard of the Long Beach Grand Prix? The Macau Grand Prix? The Detroit Grand Prix? Sports cars use street circuits, GT Sport had no good reason for not putting them in the game. Unless of course if giant skyscrapers and large amounts of detailed buildings proved too demanding for PS4 hardware, with 16 players on one track.
I don't fully agree with you on the physics. Maybe you need to improve you analogue stick skills and add a bit of throttle feathering to your game. I don't have a wheel either and I've never felt any major disadvantage? But i imagine if i did invest in one it would make me a much better player.
I don't think you understand what I mean. The Go-Kart in GT Sport, requires a very specific driving technique to be competitive, that is IMPOSSIBLE with a controller. The reason I know this, is because I have played the game extensively with both a wheel and a controller (which I prefer because I play every other racing game I own with a wheel, and GT is more enjoyable with a controller).
The technique goes: Carry as much speed into a corner as possible, tap the brake just enough to avoid going off the course and to shift the weight to the front tires, quickly turn-in to unsettle the rear tires, and the get back on the thottle as soon as you hit the apex. You will then be able to go around most of the corner, with the throttle flat on the floor. This has the most advantages on tighter circuits with hairpin turns like Tsukuba and Brands Hatch. The reason this is impossible with a controller, is because you can't 'whip' the steering input fast enough on turn-in to get the car into a micro powerslide state. There are other cars I've been told (particularly some of the HyperCars, and Gr. X) that are also really hard to drive with a gamepad, but I have yet to try it for myself because I don't feel like spending the credits on those cars. The point is, These problems shouldn't exist in a simcade game where most of the player base is on a controller. ESPECIALLY on a game with a ranked competitive mode.
I was a little shocked to see the endurance races dropped from GT Sport but my PS4 certainly wasn't. There are a number of reasons why these may have been left out? I'm assuming that it simply may have been down to them not being very popular. Its a great idea in terms of realism - to have a real race that takes 24hrs to complete, but maybe that kind of heavy grind just fell out of favor among the majority of gamers? And without this type of race B Spec is pointless.
It could be more popular if they evolved the mode to have driver swaps as a co-op feature... but they thought cutting it our all together was a better idea. (this critique is also one that I have against GT6)
Again GT Auto was nice gimmick, and car tinkering is still in GT Sport to some capacity. However the option to add spoilers to cars might be missing due to the majority of Sport and Race cars already coming fitted with them.
I hope you realize Gran Turismo Sport isn't the only game in the series to have a large amount of race cars with wings preinstalled. Again, this isn't a good defense for content cuts. We had the ability to add wings in the 2004 release of the game, a game which also had many race cars.
Cant accept the AI statement... sorry. You are majorly discrediting yourself.
I suppose there really is no way of convincing you otherwise. The fact of the matter is, GT4's AI was from a game released in 2004. GT Sport's was from a game released in 2017. I would take GT4's sporadic (but fast) AI, over GT Sports mannered (but slow) AI, any day of the week if it means not being in 1st place by over a mile, in the same cars as the competition. I prefer to be raced, not be handled with kids gloves by the AI because the game assumes I have never touched a racing game in my life.
Keep in mind, I never claimed GT4's AI was the best (The original Automobilista on PC has that award imo). My argument is, that GT Sport's AI took one step forward by making the AI drive cleaner, but two steps back by somehow making the AI much slower than what we had 15 years ago.
A lot of the multiplayer stuff you talk about is out dated due to the advent of access to broadband and popularity of online play. You can still apply restrictions to lobby's and there is nothing stopping you from communicating with other drivers and properly managing rooms.
I'm sorry, but your ignorance is really showing here. You can't limit what type of cars are allowed in GT Sport open lobbies. The only restrictions you have is weight, power, tires, and class restrictions. (and in case you didn't know, GT Sports N-Class system is completely broken). None of which allow you to restrict what cars can, and can not be entered. It was a standard feature in the only other two GT games with multiplayer, and GT Sport cut this from the game with no explanation. Have you ever noticed the ton of lobbies in GT Sport that are titled 'STREET CARS ONLY, NO GR1,GR2, OR GR3 OR KICK', 'RACE CARS ONLY OR KICK', 'JDM CARS ONLY, NO MUSCLE OR RACE CARS'
To make things more frustrating, I have seen players often swap to a disallowed car at the last second before a race starts, just because they know the host most likely won't be damned enough to back out of the race to kick them out.
I challenge you to start a Gr. X Super Formula open lobby without someone trying to bring in their Gr. X Tomahawk or Gr. X Mercedes F1 Car at least once in a session. You will be surprised how many people refuse to read Open Lobby titles, or just love blatant trolling.
You sound majorly disappointed with GT Sport which is a great shame. Maybe you are a little bit stuck in your old ways?
Actually, I wouldn't have such a negative opinion of the game if they didn't have the nerve to charge $60 for the puddle the game released as. I'm happy I waited to buy the game, till I could find it for a cheap price in late 2018 (which ended up being $10).
Overall, I love the livery editor, the creative content sharing, the diverse driving feel across all cars, the new sounds, the amount of detail in the car models, the new suspension physics, and much more. A new evolved GT Mode, car part tuning, GT Auto, and a proper open lobby editor is all that is missing to me. If they can include all that in GT7 while keeping the new eSports fanbase satisfied as well, I'll be happy. It may even end up being in the running for the best GT game, who knows.
). I can't say it any better, as mentioned above, about brands like Ferrari and Porsche, had they been in GT4. 
. People who take the plunge and decide to invest there money into a console are more committed gamers, and shouldn't really be thinking 'not wanting to deal with online crap', this is now the new normal. Just like how everybody who is anybody (including your grandparents) has a mobile phone.
