Tribes: Aerial Assault, to me, is fun; I think the online playability is a ton better than SOCOM.
There's no real online chatting in T:AA, but you've got different ships and jobs to do, whether it be repairing damaged equipment or running in light armor to Capture The Flag.
For newbies, there's lock-on mode, so that helps... and eventually, you get better at it. I didn't think I'd like CTF that much, but as I got better, it's my favorite mode. I'm still getting used to DeathMatch/Team DeathMatch... but sneaking in and taking that flag is great.
If the release dates hold -- although, of course, they rarely do -- there are quite a number of promising titles on the way next month: * 11/4: Dynasty Warriors 4 - Xtreme Legends Another add-on pack for Koei's beat-em-up franchise.
