Yeah FM4 is honestly worse than FM3 just with better physics i suppose but nothing major that will make you want the game.
I only play it coz its the only racing sim on xbox, but the whole game is shoddy and done seems like T10 just said "that'll do". You may blame the limited time they have but that doesnt excuse the backwards movement, not fixing any bugs just creating more which is the one tging that I think they need to do before they even start making a new game.
