I'm getting pretty sick of Halo 2, and I'm looking for something else to play on Live. So far I have tried Men of Valor, Rainbow Six 3, Ghost Recon, Counter Strike, and XIII. I didnt really enjoy any of them. Men of Valor and Ghost Recon made me feel like I was shooting at dots, all the players are so far away and look so tiny, it got very frustrating. Rainbow Six 3, and Counter Strike all annoyed me because whenever I die, I have to wait for my teammates to finish playing to be able to play again. XIII plays way too fast and there are hardly any people playing. The one I am almost certain I would like is RTCW, but I'm not sure how many people are playing that still.

Anything else out there that I should try? I was getting excited about Brothers in Arms but apparently that game is only objective based, and my least favorite thing to play on Halo 2 or any other FPS is CTF.

Don't know how good it is, but Goldeneye : Rogue Agent is $9.99 new at EBGames.com (or at least it was yesterday). For that price, I'll give it a try.
edit : It still is

Doom 3 and Unreal Championship 2 are certainly the other best FPS on Live right now.

Castle Wolfenstein is really good, but who knows if anyone still plays it. Area 51 has some nice modes as well.

Ghost Recon 2 is a GOOD improvement over the first one.

Pariah is fun...map editor
Timesplitters is really good...map editor also.

Doom 3 SUCKS on LIVE (4 players max...no real options)...unless you want Co-Op
GoldenEye was fair....worth the $10
UC2 was ok...I did not like it though, a bit fast and did not prefer the melee combat

I loved the first Ghost Recon games (the original and Island Thunder) but don't care for GR 2 at all.

Rent both, they are very different.

I'm thinking of checking out Republic Commando for Xbox - anyone try it? What did you think? Just watered down Rainbow Six, or can it stand on its own?
