I’m not really sure how to categorize this one – it’s not an arcade game but it is something that could be considered out-of-home entertainment. In Japan, Sega is testing out this new urinal game and so far it sounds like it’s a hit on location test.

Versus City has more including a second video that’s most likely NSFW.
