Topic: any game you like so much you own multiple copys

I don't often double-dip. Off the top of my head, I do either repeatedly own or plan to own the following:

SteamWorld Dig - Wii U and 3DS
SteamWorld Dig 2 - Switch and PC (As it was briefly free on Steam recently)
A Link to the Past - GBA and SNES Classic
Super Mario Kart - SNES Classic, N3DS VC
Super Mario RPG: Legend of the Seven Stars - Wii U VC, SNES Classic
Super Metroid - Same as above
Earthbound - Same as above
Super Mario World - Same as above
Secret of Mana - SNES Classic, Collection of Mana
Twilight Princess - Wii, Wii U
Oracle of Ages - GBC, 3DS VC
Super Mario 64 - Wii U VC, SM3DAS
Super Mario Galaxy - Wii, SM3DAS
Link's Awakening - 3DS VC, Switch, soon Zelda G&W
The Legend of Zelda - 3DS VC, soon the Zelda G&W
Zelda II: The Adventure of Link - Same as above
Skyward Sword - Wii, eventually on Switch (Love the original, but I have such a backlog that this isn't high priority)
Super Mario 3D World - Wii U, eventually on Switch (Same excuse as the above)

If we're counting Pokemon remakes:
Pokemon Diamond - DS, Brilliant Diamond soon-ish
Pokemon Ruby - GBA, 3DS (Omega Ruby)
Pokemon Silver - GBC, DS (SoulSilver)
(LeafGreen would theoretically count too, but the original Green was Japan-only....I still own *Blue though)

One that used to count would be Assassin's Creed IV: Black Flag as I now own the Rebel Collection on Switch, but the trade-off is I sold the Wii U copy a few months ago.

Kid icarus physical / digital. Shouldn’t have to be that way but that’s how it goes..

Overwatch - I own the PC, PS4 and Switch... But lately I only use the switch version.
Diablo 3 - PC and Switch
