I'm enjoying it... a lot. And it totally surprises me. I'm not much of a twitch, multi player gamer nowadays, but the game really has been great for me so far. Tough getting started, and I die waaayyy too much but I'm learning.
Just sitting on top of a mountain looking down on a raging battle is quite a sight. Knowing all of those tanks, aircraft, machine gun blasts going off are other players going at it is impressive.
My one concern is lasting appeal. You win hard fought battles, take territory, take over huge parts of the map, and within an hour it can all be gone. So it leaves me a little empty in that respect. So then the long term appeal comes back to you fine tuning your character and finding a great group to play with. So we'll see how it all turns out.
Give it a shot! Even if you're an old, slow, feeble gamer like I am, there's fun to be had.
