This is old news but I forgot to post it. Tribes: Ascend has gone into Open Beta. The game is free to play with the option to buy credits(gold points) to use to unlock abilities and class combos sooner than later. The game is fast paced and very fun. It actually is starting to feel like the old Tribes 1 game Zancarius and I played the hell out of but much prettier. I wouldn't mind partying up with some guildies sometime to play this game. It does a pretty good job of matching players up with others to play the game against so you aren't left waiting for things to shoot, defend, or capture.
I do recommend practicing with skiing and using the jetpack as well as vehicular combat. With a little practice, its really not too bad. The game does a good job at showing you how to play thanks to the tutorials and tips.
