You can try playing CompuWars...it's really dumb, but it's fun to go around and beat up big Microsoft Juggernauts. And, like Lonevoinian said, ROTV and ROTV2 are really good plugs. Also, of course, I'm making a large plot expansion, but it's still not near complete. Try the Star Wars plug, too. That's pretty good. Of course, it is a TC, so I don't know if you wanted any of those. The best idea would be to just look around the (url="http://"http://www.ambrosiasw.com/games/evo/addons.html")add-ons page(/url) and see if you notice something interesting. That's what I do most of the time when I'm bored.

I can't think of anything else to write...
