The game has a lot of promise. My initial thoughts are that they have done a decent job with balance. This isn't like the Battlefield Vietnam game where you had a server full of marines with the m60/bazooka combo (bleh). All the classes seem to have their ups and downs, and the sides seem well balanced with vehicles too. It will take time to see if any maps are broken, they look pretty good so far.
Choppers are good fun, but much different than in Desert Combat. Easier to fly, but that ease took out the ability to do some of the more trick manuevers as well.
Jets are okay, but just not my style with this game. They're very fast and the maps seem a little small to really make them fun.
The commander position is pretty slick. It really lends itself to teamplay. The fact that you can also squad up is also awesome. This game is definitely a clanner's game. Matches should be a team player's paradise for sure.
As for the gameplay itself, I'd say it's good, but not great. I'd like to see the first patch released as well as the 5.7 catalyst drivers for ATI before really commenting on the gameplay. A lot of the servers with decent pings still play buggy, which makes me question if they need to tighten that up in an early patch. The graphics are nice, but nVidia's close work with the game means ATI cards are behind the curve on performance. I've heard the brand new Omega Drivers for the ATI cards give a tremendous performance boost to the game, but I prefer to stay with the catalyst drivers.
All in all, a lot of fun with tremendous potential as the game patches itself, the video drivers get updated, and the community learns the finer points of teamplay.
