The Most Duplicates You Own of One Game

[Nz17]

For me, probably Sonic The Hedgehog 1. If we are including SEGA Game Gear (4) and Genesis / Mega Drive (12), that is probably a total of 16 issues of the game/s including legitimate tangible and legit digital copies. That number includes compilations and mini consoles. This does not include sequels.

Probably my manufacturer's box of ten copies of Wonder Project J2.

Years ago I was being pressured by the owner of a pawn shop who was really trying to get me to buy a big box of Atari cartridges. I only wanted one or two games, but he kept up the hard sell to get me to buy all of them, even though about three-fourths of the large box were copies of Combat. I didn't buy anything. I already had maybe ten copies of Combat, I certainly didn't need more.

I probably have three copies of SNES Wario's Woods and three SNES Tetris 2. At least with Tetris 2, I got two manual variants I was able to scan for preservation (though I think I only scanned the pages with minor differences).
That reminds I also scanned the manuals for Y's V and Y's V Expert for the Super Famicom. Found out the only difference I believe was the cover. Definitely not worth it to buy a complete copy of Expert if you're into buying SFC RPGs.

Probably over the course of my life it was Super Mario Bros. I have Super Mario Bros. Deluxe for the Gameboy Color and 2-3 copies of the NES version.

Not that many now that I think of it.

I have 2 copies of Combat for the Atari 2600.

I have Super Mario Bros. for NES on both the 2-in-1 with Duck Hunt and the 3-in-1 with Duck Hunt and World Class Track Meet, as well as Super Mario All-Stars.

I have The Legend of Zelda: Ocarina of Time as the original N64 cart, on the Gamecube as The Legend of Zelda Collector's Edition, again on the Gamecube as Ocarina of Time + Master Quest, and the 3DS remake.
