Sins of a Solar Empire

[aegisx]

It is meant to be multiplayer. It is a real time game, which can be saved. When setting up a multiplayer game, you can make it small enough so it will last an hour, or large enough to last months. Although I don't think the tech tree really changes, so at some point it runs out.

I watched some beta videos on it, it does seem to have some merit as its own game rather than another MOO/SE/Galciv type.
