I know the last three are probably a stretch to find out as the systems are still "new" but I so far can't find a cohesive list of what Wii U and PS3 games are considered rare that aren't full of Collector's Editions. One list on Youtube states a title is "rare" while another on Google states otherwise.

So far I beleve two of my PS3 games ( Folklore and a Japanese import of Class of Heros 2G) are rare finds and MAYBE the standard Toyko Mirage Sessions for the Wii U ( I know the Collector's is) unless the switch port effects that. I also suspect the Darkest Dungeon Switch port might be one of the less common Switch finds down he road.
