I’m sure that arcade cabinets and other such things have been suggested before, but this idea takes it one step further: full-on condo games that utilize the layout of your condo. These condo games could be watered down versions of existing game worlds, like a small Minigolf course inside of your own condo, or could be completely original. With custom condo layouts already confirmed, the possibilities are endless.
Note: I know there’s another/more example(s) of this somewhere from another game, let me find it and I’ll post it here. Found a few. Surprisingly Playstation Home was the only one to do this, or so it seems.
