A new request..

Alright, I would like to have some suggestions for a game ( MMORPG or other) that has the following characteristiques:

-The game can be played online and you may interact with others

-Player created civilisations that can develope exponentialy

-Not like StarCraft or Warcraft where you build a town only to need to restart a game after you have won/loss the scenario.

-Thought of Spore but I heard it does not implicate a high ammount of strategy/depth

I would love to hear your thoughts and if you think you have any other game that might spark my interest go ahead and tell me

Thank you for your time
