Best XBLA game

[Zomboid]

I have a shitload of arcade games, but few of them are XBLA originals. TMNT Arcade, Streets of Rage 2, Golden Axe, Altered Beast, and shit like that are all fun, but a lot of those can be found on that Genesis Mega Collection and you likely won't find others playing them online anyway.

I'm more interested in originals. Downloading old games for money seems like a rip off to me.

Unless it's an old game that I never played, and it's not actually that old.
