This game has more Battlefield moments than all Battlefield titles combined.
Some warnings though. It's an MMO which means a lot of stuff is not in the game yet. Most notoriously a mission system that should help new players get some direction. It's also missing a lot of meta game content that allows for a more strategic game experience. These will all be added though and should not stop you from having a blast already. Just make sure you join an outfit or team up with others to get the best out of this game.
Btw: This hilarious video gives an excellent idea what it is to join a team an get thrown into the action of PS2: http://www.youtube.com/watch?v=fNR4S5fZvw0
