I personally am addicted to EVE-Online
I love the depth of this game and the fact it's one of my favorite genre's also it has a fantastic community and is ever-changing.

Does anyone else play these games and why do you like them?

The good MMORPG s require a monthly fee and i dont like the idea of buying a game and then paying each month to play.
I tryed Guildwars because it was free to play but once you've leveled to the max the game becomes a bit stale unless your in a guild and take part in the team vs team and leagues.

A few years ago i was into FPS games and joined a few guilds and took part in the league matches. That can be fun, especially if you get realy good and every one knows you.

The next game im looking forward to is medieval 2 total war.
