I'm going to recommend some widely different games below.
1) The Witcher + The Witcher 2
2) Dota 2 or League of Legends (Why has no one mentioned this yet? Was there something I missed in the OP?). LoL is currently the most popular game in the world, and Dota 2 is similar but different. You might love one of these.
3) PlanetSide 2 (Just came out last week. F2P MMO FPS. It has a hugely steep learning curve, relies heavily on big team battles.)
4) Spiral Knights (it's an online F2P multiplayer co-op game (with PvP arenas too) that plays fairly similarly to The Legend of Zelda: Four Swords Adventures. It's super fun if you get into it).
