Good System-Link Xbox games

[anvil82]

I was thinking of having some people over to play xbox games, and I want to know some good xbox system-link games.

I have crimson skies and that is a great system-link game.

I want some halo type games.

I tried Rainbow Six 3, but you can only play 1 person per xbox which is stupid.

Is soldier of fortune II the same way, or can you play split screen?

What about unreal championship?

Thanks.
