Wat game is better(for xbox360)?

GTA4, FALLOUT, GEARS 2 are AWESOME!!!!! burnout paradise is ok for a while but gets really boring. tf2 and portal are pretty cool to but not cool enough to be in caps. viva pinata looks gay so i don't have it. madden is pretty cool but it is just like all other 20 maddens, skate 2 is cool for a while. never played shrek (looks dumb) or sonic (same concept in every game) half life is also cool. and never played frontlines. ok that's all the help i can give hope its enough
