Absolutely Addictive

Globulos is a deceptively simple and utterly entertaining Flash-based game. The kind of thing that could suck up hours on end (if you let it, which you obviously shouldn't, but probably will anyway).

Oh, and if you happen to find yourself up against "GroovyRoovy," go easy on me.

Update: My brother-in-law, who is studying economics, informs me that this game is a nice example of a Nash equilibrium, which means it's not just a waste of time; it's educational!
