If you have the time, you could try EVE online, it's massive pvp multiplayer game like WOW but is much more flexible. It is staged in a space universe; you can have faction wars to conquor territory in the game, sabotage, spying, alliances, different space crafts fit for different purposes, guns, armors, drones, skills, maintain relations with factions, a completely free market - it is actually profitable to set yourself up as a merchant. Ofcourse, there are still friendly zones for rookies, quests, ai ships to shoot and scrap for valuables, but the end game is huge. Unlike WOW, everybody plays in the same universe. Instead of breaking the game up on many servers, they've chosen to let different areas be controlled by different servers.
Biggest asset/annoyance besides beeing a non-free game, is that it takes so much time. Not exactly in terms of gaming hours, but gaining skill takes real life days, so be ready for years of gaming experience!
