Random thought pertaining to Hetalia, Prussia, and Amnesia.
I think Prussia would play this game. Not because it’s horror, but because it has him in it. Earlier in the games, you discover a map of the Kingdom of Prussia. (I can get a screencap if needed) and then later, there’s some sort of flag/crest with the black eagle:
(Sorry if this is a slow realization that the castle is located where Prussia used to be. I’m so derp.)
But, yeah. Prussia would probably play them because they remind people about him.
(Random thought that occurred to me when I spotted the flag in PewDiePie’s play-through of it. Carry on. xD)
