I don't know if I was bored or something to think the game would only sell 375K units. Perhaps I thought these were Japan sales only, or back then the free game deal or the Wii U bundle weren't announced. Either way, I was so far that my prediction looks like trolling xD
My bet with The_Liquid_Laser: I think the Switch won't surpass the PS2 as the best selling system of all time. If it does, I'll play a game of a list that The_Liquid_Laser will provide, I will have to play it for 50 hours or complete it, whatever comes first.
