This may be selfish of me, but I honestly don't care if Physical games have a premium cost because of the cart - and they seem to have that Switch tax. What I DO care about, though, is the cost of digital titles being the same as other platforms. So far, the costs on the Switch are higher on a growing number of multiplatform games, and the price of the digital eStore versions match the inflated costs of the retail physical version. That's a major problem.
Puyo Puyo Tetris is the only game to release at a different price point: $40 retail, $30 digital (matching the price on other platforms). Evidently, that's because it's releasing as a "special retail edition" with a couple tangible goodies thrown in.
I want to buy 3rd party games on the Switch, but as long as this Switch tax is present on the digital store front, I'm not going to be giving anyone my money for those games.
