I wonder what kind of legacy these late Wii Just Dance releases will have years from now from a retro game collecting standpoint. On one hand, they're Just Dance games which are effectively worthless unless you're going for a complete Wii collection. But on the other I can't imagine that games being released this long after a system was discontinued are made in large quantities so they might end up legitimately rare. So you end up with a rare title that few retro gamers would really want to play that's a common title on another system. That's an odd scenario. I guess if it ends up being really rare the price will be high solely from collectors wanting every Wii game. Stadium Events on the NES is worth thousands but it is literally just World Class Track Meet, a game that costs only a few bucks, with a different name. No one is driving the price up just to play it, but enough collectors want it and the game is rare enough to inflate the price.
