Just thought I'd see what kind of online games you ladies and gents are migrating from (or planning play at the same time for the masochists).
I'll happily start.
I'm from EVE Online, retired about 2 years back, played since it's beta before that.
I loved the complexity in that game, the politics, comradery and coming back from the brink.
Things got dull in the end when ISK becomes meaningless (I'm a type of player that rarely finishes a game and enjoys the struggle).
I love the extra freedom the vision of this game promises.
All the best!
