Borderlands bundle was $6 (97% off) 2 days ago on Steam. Today it's $60.
For some reason when a game is free I'm like "well its free, I can download it some other time." But when its 97% off I buy it. Brains are dumb. :)
I installed 2. It says it has co-op. Maybe I'll play it someday.
Bundle sales appeal to the completionist in me. Very dangerous.
Half my games I can't play unless I boot to Windows, which I rarely do long enough to remember that I have games.
