>>37869795Do you own every Pokemon game?
Yes, I do. I have between 2 and 5 copies of everything up through US/UM.
>How do you display them?For the most part, I don't display them. I have various shelves in the room surrounding me for storage which I guess technically displays them but the majority of my collections are stored away, mostly keeping the ones I'm going to play within reach.
>Are aftermarket cases a good choice?I wouldn't really say so. When I do have them at hand they're all in their original packaging. I have the boxes and everything they came with for most of my collection (the exceptions being Mickey's Speedway USA for the GBC and Pokémon TCG - their boxes got lost in a move in 2001 and it would feel wrong to replace them).
The only exceptions to the original packaging rule for everything else are the Pokémon GBA games since they have a slot for one meaning they take up less space having them nearby.
My main Ruby is in Diamond's box, Sapphire is in Pearl's, Emerald in Platinum's, FireRed in HeartGold's and LeafGreen in SoulSilver's. I just leave their boxes and shit stored away.
If you prefer the look then you really shouldn't care but original packaging is always preferred in my opinion.
