Is Forza better than GT? I had forza for the first xbox and liked it. thinking about getting 360 now that its cheap
GT is better than Forza in some aspects (shaders, drifting physics, steering wheel support) but overall Forza is better and more fun.
I have played thru every GT except 5 because I don't have a PS3 and my friend didn't liked Prologue so he just rented 5, and also have gone thru all 4 Forzas; I'm talking a HUGE chunk of my life (well over 600 hrs between all of them) spent on those games.
I still have a soft spot for GT, but I feel like they dropped the ball on 5, and Forza series has matured amazingly over the years. the jump from one game to the other is brutal in therms of physics, gameplay and graphics.
Unfortunately the lack of support for steering wheels (only Microsoft and Fanatec) and the fact that you need to buy a shitload of DLC to have a complete experience can make you think twice.
For solo using a good steering wheel setup, I would recomend GT. For something more casual and online, Forza (doesn't mean that it's a shallow game, just that is more user friendly for everyone)
