I have a decently expensive collection just by virtue of being a gamer my whole life and being someone who never sells/trades in their games. I’m frequently shocked by the price of a lot of the games I own (especially some of the Gamecube games) but I have no idea which one is worth the most.
Some of the most expensive games I have off the top of my head would be: Conker’s Bad Fur Day for the 64, all the GBA mainline Pokémon games, Heartgold/Soulsilver/Platinum on the DS, Chibi Robo, and Pokémon Colosseum and Gale of Darkness on Gamecube. I also still have the box for Soulsilver in mint condition lol it’s just such a nice box and also a remake of my favorite (and first) Pokémon game so I kept it all these years.
