Warhammer Online or WAAAGH!!!
Playing on the Forest (Destruction) and Pit (Order) servers. I FRIGGIN LOVE THIS GAME! Its everything I wished World of Warcraft had been. RvR (which is like PvP Battlegrounds in WoW but actually, you know, matter!) is a blast, but the star of the show are the Public Quests. Its like a raid for EVERYONE all at once. You don't have to even participate through the whole thing. Jump in and help where you can, get rewards for it later. Every time you do it, you build up points to buy nice gear with, just like you would get rare drops in a raid. The top players at the end of the quests also get rewards on top of that. Awesomely fun stuff!
