For Pokemon Titles on the 3DS, I started buying both versions because I moved to Japan. I bought a North American copy of one and a Japanese copy of the other. That way I could get the event Pokemon for either region. X/Y, ORAS, S/M, US/UM. Though, I stopped doing that with SwSh. $60 is too much. Plus, with the Switch, there's no longer any difference between games in different regions. Any event Pokemon should be available on any version of the game. But also, I started losing interest in the main games.
