That's what vehicle upgrades and tuning is for.
I still prefer that to GT7's system, because you at least know
exactly what you're getting for what you pay for, whereas with GT7 you likely are going to overspend on the MTXs to get the credits needed for a car.
You literally get wheelspins every time you level up, you earn double credits for races if you've bought the VIP pass (as well as 2-4 free Super Wheelspins every week), there's a house that you can buy that gifts you a wheelspin every day, some of the car collection rewards are additional credits, several cars have their own credit boosts, wheelspins and XP boosts, and there are several challenges that earn you Wheelspins, Super wheelspins and credits as rewards. You can also get money through passive means by creating and sharing user-created content, such as liveries, tunes, custom events, etc. That one is admittedly luck based,
although several or the more active Forza GTPers have come together to more-or-less cheese that system.
Let's also not forget that XP and credit rewards are scaled with race length, meaning that longer races yield higher money and XP rewards, the latter of which can grant you a good number of wheelspins, further boosting potential money earned.
As mentioned, longer races reward more credits and XP. Some of the Forza Edition cars also have Skill Boosts for certain actions, and banking those skills also rewards more XP at the end of races.
Then all you're doing at that point is arbitrarily making the game harder for yourself. You've consciously chosen to ignore one of the options the devs have given you towards earning a particular car. Hard to see how that's their fault.
That's also not the same thing at all to GT7, which requires you to grind unreasonable hours on one event or fork over 2-3x the games worth in real money for the same car.
Yes, because PG understands that there still needs to be some sort of balance when it comes to earning cars and money. The issue was that people were buying up the Willys Jeep in droves because it had a reward box that gave 3 Super Wheelspins, then players proceeded to flood the Auction House and gifting system with Jeeps.
The only real issue I had was that when PG fixed this, they called it an "exploit," which was a bit silly since all the steps needed to engage in it were systems being used in the way PG initially designed them to be used.
Primarily because the game without MTXs is set up in a way to where you're constantly getting rewards for playing the game, has a large variety of ways to earn said rewards, and the overall economy isn't setup in a way to nickle-and-dime players at every chance it gets.
What's really funny to me is how some people's argument to the complaints about GT7 is "just play the game," yet when PG sets up ways for people to get what they want in a reasonable way
by playing the game, suddenly they're the bad guys?
That' actually not really a thing anymore. Legendary creators
can sell cars for a tiny bit extra, but now what influences how much cars can be sold for is based on a cars relative rarity within the game. Right now the maximum Buy Out Price for the McLaren F1 on the Auction House is ~7 Million credits, however several listings have the buyout price at 1.5-2 Million Credits, and there's a pretty healthy number of listings. Since it was a reward during the first Series, this means that lots of people have it, so there's not a whole bunch of people bidding on it, meaning you can likely grab one pretty cheap.
