I cannot find any MMO version of the civilization series.
Specifically what I am looking for:
-Technology tree from the stone age to at least our current days
-At least 100 players in a map
-City management but not too much micromanagement

Can you give any suggestions?

Facebook's civilization?

I only played like... 30 seconds, hadn't had time, so I have no idea. Taking a look won't hurt, but I think it's a lot like other "social games".
