Well, I tried it. I have to say I like BF2 better.
Gameplay is the typical "team-FPS". This typically means that on "assault" maps the defender outnumbers the attacker 1.5 to 1, and the "defending" team ends up camping the "attacking" teams spawn point.
A couple maps seemed interesting to play, I had fun on Odessa and Krazny whateverthehell... both of those seemed a bit difficult to get to the spawn to camp it.
The "meeting engagement" type maps can be interesting, except all the ones I've played on so far involve mainly vehicles, which I'm not that into with this game. They are hard to see out of, and 1-2 hits will kill a tank.
Bottom line I'd say, if you are on the fence and already have a FPS you can waste some time on, don't get this.
