Overall very good strategy game but I gave it three stars cause I think it still needs some improving. First there is no sound. I mean, really no sound to the game. No music and only a ancient beep when you try to move on a impassible tile and another annoyance is when the computer attacked my city, I didn't even see the units coming or see it happen! But besides that the core strategy of the game is fun. Trying to get your ship back to Europe to train some experts, exploring surrounding area, trading with natives. There a lot that happens. I think with time, as they improve on the game this will be a definite gem to the open source gaming world.
