So question based on this thread. Do Crowdfunded sales count in stats like these? I mean many people would have already bought the game and asked for it on their prefered platform. When this game was first Crowdfunded, the Switch wasn't even out and the option for your copy to be on Switch wasn't available at the time.
SO... the high sales for Switch version is because many of those who pledged got their copies on other platforms already and don't count in sales.
Still wouldn't expect it to outsell both of them so that's great but just a thought.
