XBox system link : best games....

I needed a 3rd controller for my xbox recently, and was amazed that I could pick up the following for only 30 quid:

XBox, controller and six games!

Had an old hub and a couple of RJ45 cables, the two xbox's linked no problem. So far I have Project Gotham Racing 2 on link-up. My (very) shortlist for system link play is:-

1. Rogue Trooper
2. Halo

Anyone have any other suggestions ?

i thought you didnt need a hub and it was cable to cable for 2 xboxes hub for 3/4

initially tried just cable, not for long, but ended up using the hub. got halo and PGR2 on system link.... not a patch on my end zone trucking.....
