Tribes: Ascend took the core of Tribes 2 while making changes and tweaks. Not all of it is good, but it's still a very fun game that has one of the best Free to Play models I've seen. All weapons and classes can be unlocked with XP which isn't hard to earn once you learn the ropes and don't die every 20 seconds.

Surprisingly a really fun game. I thought GTA IV was only decent, so I wasn't sure what to expect with this one. Pleasantly pleased with how much fun it is to just jump in and run around doing missions. Co-op is a blast and being able to join a friends game in progress on steam leads to fun times.
