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.
