I'm seriously not trying to thread derail or anything, as I love the Switch and think Darkest Dungeon is an awesome game. But, this game is $5 on iPad...like, always, not a sale thing. This price difference is huge even when factoring in the Switch Tax.
EDIT: I get what everyone is saying about it being a different market, but I think the amount of crossover between the two install bases (iOS and Switch, that is) is probably greater than you think. Hey, I already own the game, anyway, and I think it's great. I just want to see Switch versions of games have success, and this price seems prohibitive in that regard.
