It is. Best thing is that like how FPS games have classes (anti-tank, sniper, etc.), this game has different roles. If you choose to play as Support, you get anti-air, a demolition engineer, artillery, and so on to choose from. If you play as Air, you get helicopters. Armour gives you tanks. And so on. So you have to build up a team of varied roles and work as a team to get them to work. C&C Generals' expansion pack had this, but never took it nearly this far as every 'Commander' was self-sufficient.

The fact that trees, bridges, houses, and so on can be destroyed like in RTS games sounds quite great, too, as do the game modes. I'm so buying this when it comes out.

For an idea of what the game is like, I recommend you get Ground Control free (and completely legal) from FilePlanet. There's even an SDK out, at massive.net, if you want to resurrect the game with some modding. I always dreamed of a GC-> Star Wars Total Conversion .

I know the feeling. I once wondered if I should start a GC mod for BF2. I even jotted down some notes on what the classes could be, how it'd work... but no, never came to fruition. I hope someone else picks it up some day.

I'm glad for your sake you feel that way. My problems:
-Different stances instead of special weapons.
-Reinforcements and control points.
-Level of customization.
-How the plot got eerie late in the Crayven campaign and the feeling increased as you played through the Order campaign.

I wrote a good deal more about GC in this thread, in particular this post.

99% of mods do, in my experience. As a matter of fact, I don't really get excited when I hear of new mods anymore, I just think, 'oh well, it's going to collapse in a month or six anyways'. Even when mods seem to be moving along perfectly, like FS is now, I'm anxious, halfway just waiting for it to grind to a halt and be abandoned. The high failure rate, I suppose, comes in a large part from people not realizing how much work modding is. Better to start small, with a mini-mod, and then gradually work your way up. I learned a lot from working for Warp, but I learned even more when I made my little mini-mod for BF2 that did little except make all wrecks but those of planes and choppers stay for five minutes. It never got released, but I was proud of it, and it was big fun.
