my thoughts:
it was pretty sweet... but i have a few problems.
1) there was a lot of graphical glitches in the menu (it made it really hard to use the menu most of the time)
2) my teammates ai was crappy (while sometimes they would go in tanks and attack, most of my team - 2/3 of them would stay at the base and do nothing)
3) not enough vehicles! there was only 2 tanks (i think, maybe less) for each side. no planes, no ships. nothing more.
4) it was a very big map, but there was limited scenery (although it was desert). it was just the outposts and barriers, and that was it. i expect a little more stuff to hide behind!
5) only ONE map?! i waited 40 minutes to downoad, 15-20 minutes to unpack and set up, and all i get is one lousy desert map with no multiplayer and only instant battle? come on... i cant really get a feel for the game from this...
aside from that, it was cool. it was easy to go in and out of vehicles, and it was easy to steer and shoot using the tanks. also, graphics were pretty good, i had settings on max and there were no slowdowns.
