Empire is a browser strategy game by Goodgame Studios. In Empire you can build your own castle and create an army for conquering the world. As you fight against other players in a constantly changing world based on player actions, it's up to you to rise above everyone.
Empire by Goodgame Studios in Germany is an MMORTS played across three Kingdoms much in the same vain as Travian or Snail Game's Ministry of War. It has all the hallmarks of RTS games - you build your base, farm resources, recruit soldiers and do a little raiding of your neighbors for fun and glory, not to mention swiping all their goodies.
