If I buy a game in store X, and it’s available on store/platform Y, I should be able to play it on both.
Unfortunately, I don’t think that’s the case.
I recently bought a Nintendo Switch, and although I’m happy overall, some games have very heavy limits built in (think: max number of units in games), and they’re also available on PC/steam, but I would have to buy the games twice. I just can’t get over myself to do that, I shouldn’t have to do it. At the very least make the license transferable! :)
