Mechassault 2: Thoughts?

Anyone pick up this Xbox title in the after Christmas rush? I’m enjoying the pretty 'splosions and graphic upgrades. Also the four new “vehicles” of pilot, battlearmor, tank, and VTOL makes for a fun time. But I’m having trouble getting into multiplayer games. Games are open, have plenty of spots free, and the “connect” stoplight is green, but I can’t get in to a lot of games for some random reason? Anyone else out there feeling my pain?
