I'm gonna go ahead and vote for Destruction Derby. The game is just incredible, Like double V said there's a 4 way warthog crash, and even if you fall off you get to go up into these sky boxes and toss fusion coils at the people still in there warthogs. Beat That.. I dare you.

Kill many, and you're a conqueror
Kill them all ... Ooh ... Oh you're a God!
