i have three copies of pokemon sapphire, all in different languages..........the answer? i have a problem. lol but nah idk i like having extra copies of games i really love, but it does have to be different from the copy i already own in Some capacity. either a different version, language, maybe even rebuying a game bc i found it with the box and manual (esp N64 games, back when we ain't know better and threw the boxes away lol).
i have multiple copies of various pokemon games. sapphire (english, french, japanese), silver (english, french, VC), crystal (english, japanese, VC), black 2 (english, japanese), heartgold (both english), emerald (both english), white (english, japanese), Y (physical and digital), aaand i think that's it. lol for non-pokemon, i have three versions of ocarina of time (gold cart, 3DS, gamecube...used to have a grey cart too, but needed money), two kirby (one english w no box, the other is japanese w everything), harvest moon: a wonderful life (PS2, GCN), persona 5 (vanilla and royal, though they might just count as separate games entirely since one is a deluxe lol). i think that's it...i did at one point own two tales of xillia 2 bc i bought one on my own and then ended up loving it and got a collector's edition as a gift, but i sold the extra copy when i needed money more than a box on my shelf.
