I can't speak for PS2 online since I only have a few games that use the BBA (SOCOM, CoN). If Monster Hunter would 've supported voice chat I would've snatched it up in a heartbeat! XBL is always populated with players in a large variety of games. The Tom Clancy games always have people online (i.e. Ghost Recon, Pandora Tomorrow, R63), then some of the older games have a cult following (i.e. Unreal Championship, Mech Assault, Solider ot Fortune). You can always find a game in Rallisport Challenge2, Crimson Skies, Project Gotham2, Full Spectrum Warrior, Unreal 2 XMP... just name it. The coolest community out ther ehas to be the Steel Battalion:LoC folks, talk about dedicated?! The only game that I can't players for is Shadow Ops: Red Mercury, I must be one of the 7 people that purchased a copy. Right now on XBL the hot things are ESPN NFL/NBA 2K5, Madden, Burnout 3, R63:BA, and Star Wars Battlefront.
