I started playing this yesterday and so far it seems like just the right amount of time consumption for me. The address is http://ogame.org.
The idea is to research and build, and explore new planets to colonize, while fighting other players. At the rate in which I am building it seems like it will be weeks before I even get a shipyard built. There isn’t much to the game, so some of you might not be caught, but I like something I can check every few hours, click a few buttons, and leave to do its thing.
I am in the Barym Universe (each 'verse has its own logins), so if you join add me as a buddy. If we get enough people maybe we can form an alliance, or something.
