Addictive game. Interface is very complex and the game is similarly deep.
The most intriguing part is knowing that nothing is scripted. Every little gun shot or explosion is done by human players (it got that excellent sound system Halo 3 uses so far-off fights sound different with low pop-pop-pops and whatnot, with that coming from dozens of separate fights..). It feels grand.
Where the game suffers is in presentation. Pre-game Menus look bland, framerate is not stable and it's not a super detailed game. Kinda feels like Planetside did back in the day (biiig scope, rough edges).
Good stuff.
