I'd mostly looking for games that evoke the feel of old-school video games or anything Nintendo-made. Oddly-placed item shops, multiple lives, a strange rarity of glass bottles or some other mundane item, etc.

but, really, anything video-game themed works for me. I was just curious about the concept and found that trying to Google it brought up the wrong sort of rpg, but I couldn't eliminate "video game" from the search like I might normally do.
