Iv been lurking on gaf for awhile and never posted, but I feel this is enough to post on. Iv looked around this topic and seen a ton of mis-information or misleading information.
I've got about 15 hours into Forza 5 thus far. Are some cars expensive? Yes, but you get a very decent amount of credits or even the early races. Depending on the difficulty and assists you have on even the first series races earn 5-6k each. Someone said they took out affinity. That is incorrect. After each race you earn XP for yourself and for your affinity. Also when leveling its true you no longer receive a car BUT they give you a bunch of credits. I got 30K for hitting level 2 and its gone up from there.
So while the cars are expensive making money in this game is kind of a joke, im sitting over a million credits and havent "grinded" or credits one time. Its all just gotten through the progression of the game.
All that being said if you listen to Turn 10 in interviews (Especially the one Greenwalt did with Sessler) they said they wanted the option in the game for people who wanted to avoid putting in the time. And thats fine. I never understood it personally, but hey more power to people. But you shouldnt fault a game for giving people options to be lazy. But getting some of those 4 million credit cars is going to be a joke later on as again, iv already saved up a million and thats from just the 1st few series. Money is not hard to make in this game.
