It's always funny to see what one side throws at the other, as it's ultimately going to come full circle.
F3 physics glitches, weird turtle roll over, car on nose... we will see similar problem videos when Gt5 comes around. No game is perfect and there will be exploitable glitchable areas in the game.
Look see, the thing is, its not the physics that most people are bothered about. Its the little things i would be annoyed about if i bought Forza instead of Gran Turismo (The ideal situation would be to buy both, but lack of money means i can only afford one).
Just browsing the Forza forums, and there are many many threads complaining about small insignificant things in the game that most people miss, but that affect gameplay significantly. Here are some examples:
http://forums.forzamotorsport.net/forums/thread/3090757.aspx - It seems you cannot have kmh and bhp, you can only choose Metric or Imperial, and Metric sets power to KW. Gran Turismo you customise them individually, and it is something i take for granted. It would not affect me as i use imperial, but forza didn't think it through that people are different and use different measures.
http://forums.forzamotorsport.net/forums/thread/3137581.aspx - The Engine revs automatically at the start of a race. It gives you less than half a second between the auto revs stopping and you taking over before the race starts, so its near impossible to get off the line without traction control in a RWD/FWD car due to wheelspin. This would become gradually more annoying with the more races you do. As i say it would not really affect me too much as i love my 4WD grip, so starts are not a problem. It seems there are many complaints about this affecting RWD cars in drag racing mode, where the launch is critical, and makes RWD pretty much useless for those races.
http://forums.forzamotorsport.net/forums/thread/3120120.aspx - People complaining about the soundtrack. There have been similar complaints with GT5P, but PD have promised custom soundtracks, and also considering the great variety they had in the GT4 soundtrack, so there will be no problem in GT5, it will cater for everyones preference.
http://forums.forzamotorsport.net/forums/thread/3082215.aspx - There have been multiple complaints about the lack of public lobbys. Now they are random lobbies, like we have in GT5P, unlike the good matching system everyone liked in Forza 2. To quote this guy who is complaining, it is 'killing' the community aspect of the game. We don't know what we will see with the online in GT5, but hopefully they can do better. I'm not too hopeful on that one

But at least we know there will be private lobbies, but FM3 has that too... so they are
on par for online racing at this point.
http://forums.forzamotorsport.net/forums/thread/3166027.aspx - Your precious rewind feature does not work all the time. Enough said, why have a feature that only works sometimes when you press it? Reading more into the thread you find, if you press it multiple times, it can take you back half a lap rather than the last corner that you wanted to re-do.
http://forums.forzamotorsport.net/forums/thread/3130639.aspx - This guy can't get his controller setup the way it was in FM2. A very simple issue that Turn10 will have to fix. Again GT doesn't have this problem, every button can be configured indivifually. Another feature we all take for granted, but its becoming quite rare in games these days which makes me sad.
http://forums.forzamotorsport.net/forums/thread/3146544.aspx - When buying rear bumpers it only shows you the front of the car? So you have to buy and sell parts to see each one? It was not a problem in Forza 2 as you could rotate your car in buying body parts. Even Need fro Speed don't overlook this. Very very poor... I hope PD manage to do better with their promised aero upgrades.
I could list more but i am getting bored.
Obviously Turn10 will resolve most if not all of these issues in the coming weeks/months (i think they already resolved 1 or 2 in the first patch, but not sure).
The fact GT5 was originally aimed at PS3 release and now its for 2010, and the fact that GT4 was delayed by a long time, shows PD take their time over games mean it is very unlikely we will see games with just bad design and no proper game testing at all. The problems i listed with FM3 are not really bugs, they are just things they simply overlooked, or didn't think through, and the fact a lot of these were not problems in Forza 2 just goes to show they didn't put the effort in this time. I was not paying attention to Forza on the release of Forza 2, so i am interested to know if there was any similar problems with that.
The only real thing i dislike about PD at the moment is the fact they released GT5P for a cost and when GT5 is released it will be full price. This means i will have paid £20 more for GT than if i bought Forza. But GT5P has helped PD resolve issues that would have created great dissatisfaction. I am thankful for them for that.
I think the mindset of "release it ASAP and we can patch it later" is ruining games of today. Because by the time it is patched to the level of perfection, people have lost interest in the game and move onto the sequel. Forza 2 is absolutely brilliant, and while Forza 3 has improved on many areas, it has got worse in many areas too.
I really hope PD doesn't pull off a shocker of a game like Turn10 have done.
Turn 10 is beginning to pay a lot more attention to detail as is evident within FM3.
Lol. Just lol.
Particular people being blind or simply refusing to acknowledge how good FM3 looks now (miles better than FM2) or how much GT inspiration is apparent in the game (I mean, who says giving a nod to the people who influenced you is a bad thing?). Of course it doesn't look as good as GT5 does/will, that's the equivalent of me saying Resistance 2, Fallout 3 or even MGS4 don't look anywhere near as flushed, vibrant or just plain out as good-looking as Crysis, Assassin's Creed 2 or Lost Planet does using the DX10 API, of course it doesn't. The PS3 simply has more throughput at hand as does a custom PC.
Comparing consoles that have grossly outdated hardware to PCs with new hardware is hardly fair.
I'm waiting for GT5 just as much as the next guy, hell, perhaps even moreso...but there's no reason for me to blatantly talk out of my ass and claim FM3 sucks for this and that reason when GT or other games before it have had the same exact problems.
For example...
FM3 has a retarded lap validation/invalidation mechanic where if you so much as clip a corner or the AI rams into you (and they will unless you pull off away from them) the lap can't be validated for the leaderboards; just as Gran Turismo has a retarded penalty system where pretty much the same occurs, more or less, with a heightened emphasis on the AI.
It's not directed toward anyone, but all I'm saying is I criticize equally...I'm not going to excuse one just because I like it more than the other.
When GT5 comes out you can critiscise the hell out of its faults all you like. Its called constructive critiscism. I'm not directing this at you because i know you don't mean it like this, but some people are critiscising PD for a game they havn't completed yet which is kind of out of order.
