Have I played Slender yet? No.
Will I? As horror games make my over-active imagination go into overdrive, probably not.
Unless you want a lot of monochromatic horror-themed vent art; which is not something I want.

But I rather like the idea of a dapper-dandy haunting places and leaving cryptic clues about. I'm sensing a Rule 63 cosplay in the near future... Mostly because I love wearing suits.
