I cant believe nobody has mentioned Travians here in onRPG.

Anyway travians is a lot like Travian.. BUT.. in this game you dont control the whole city. In travians you play as a citizen. You need to get job and earn money to buy houses/funitures/armors/weapons etc.. Definetely one of the best browser games ever.

No downloads or anything. Just login and play.
