I played this for the first 3 months it was released. I actually ran a fairly successful clan/guild/whatever it was called, had around 60 people before I handed over the reigns and quit playing. I really enjoyed it in the time I played it, as sometimes the battles were very even with about 50 players in each factions duking it out over one command post. However, most of the time it was hard to find a decent amount of enemy to fight, and it was hard to coordinate a decent amount of friendlies to put up that fight. The world was just way too damn big for the amount of people playing.
I do, however, remember loving to train in flying the big transporter, taking 10 or so troops to the battle, telling them to chute out just when I'm over the right spot, then finding a safe place to land my craft and join in on the battle. Nothing funner than trying to fly in and get your troops where they need to be before being shot down.
