Civ ate my brain (again)

Last night, as part of my ongoing compatibility testing of my new system - seeing what old stuff will run in XP, and what needs to move over to my Win98/DOS box - I installed Civilization II. I figured I'd play a few turns, test the music, watch a Wonder movie or two...

I really should know better. Eight hours later, way past my bedtime, I was still clicking away at the Skinner box. Must... destroy... Romans...

And now, having somehow gotten through work today, it is the hour of the napping. See you later.
