its a given that FPS's are just better on PC, i mean, what can replicate keyboard; mouse?
but as for racing games, i just cant do keyboard; mouse....the controler thing totally compliments the whole steering thing, better than any keyboard and mouse can (controllers and racing wheels, now thats a waste of money)
overall i think that if you spend 149.99 you can buy a brand new xbox, and get a controller....then purchase whatever size hard drive you want and you will never have to spend a dime on the xbox again, it cost no money to mod without a chip, and every game you rent (like fure said) is yours until you decide to delete it
.... (or if paying 6 dollars to rent a game is too much theres always other ways of aquiring games
)
