Doesn't the new Perfect Dark have 4-player split-screen action? You could give that a shot, if you can afford to get another game (those 360 games are damn pricey).
The only game I've got for my XBOX360 is that Project Gotham game, so I dunno.
...but yeah, I don't like how a lot of games are making all of their cool features online features... especially at the expense of the home-game - single player or multiplayer.
