Steam put up a weeklong Sale on the the puzzle game SpaceChem. It’s on sale for $7.49 ($14.99), which is 50% off. They just released a ResearchNet site, which allows you to create custom assignments for other people to play with. Or you can try custom assignments they’ve created. Nice way to add replayability. A demo is available.
I haven’t played this game but it’s had positive buzz and it’s been mentioned on the TF2 blog. I think there’s a couple TF2 inspired levels.
Deal runs until until May 16th at 10AM Pacific Time.
Reminds me of this geeky joke:
Scientists periodically do it on tables.
