I enjoyed the Age of Empire Games - perhaps a bit dated now but still love the concept. Anyone recommend anything similar that is compatible with Windows Vista?

the answer is by Infinity :
I still play the old Age of Mythology, it never gets old. I stop playing it for a while but always come back to it. There were about 600 or so people online in AoM when I logged on yesterday, plenty to play a wide variety of games. Personally I like some of the maps they make on that game based on other games like Final Fantasy X or Risk, as well as completely original games.

You can always play Age of Empires 3, people still play that game too.
