A copy of Gods Will Be Watching Collector's Edition that I somewhat accidentally brought to get the 90% discount from the Humble Store Build your own Devolver Digital Bundle without knowing I own the "Collector's Edition" part. I really do hate Steam games that have some kind of Special Edition or something that is somewhat separate from the base game as opposed to just being DLC I can identify at a glance to see if I own it or not. sigh

My $1.00 mistake is your gain, lucky Steamgifter.
