I didn't know they made canadian version then. There seems to be a rapid increase in the amount of canadian games lately (especially first party nintendo games), so I thought it was something they only recently did. Though looking at ebay a guy listed 5 u.s. ones for 15 each and only one sold. I'll give you $10, not sure if you'd want to sell it for that though.
Also, anyone know what a sealed lemmings goes for? There's none on ebay. I also have a sealed star tropics 2 and a sealed addams family, I think it's the first one, not sure though. I think only the lemmings has value (I saw it for 50 or 60 a few years back).
