Practice games

What game do you use to practice with when you aren't able to get on-line? I use UC2: Liandri Conflict for reaction time and anticipation. I switch to GRAW 2 for the tactical side of playing. Nothing like being sneaky in GRAW 2 and now COD4 Beta.

I can't forget the upcoming Halo 3 release. Pretty stoked about playing it. Unfortunately, I'll be out of town on vacation for the first week of release.

Later and have a good weekend!
