I made a thread not too long ago about a discussion I had with friends about a possible new game/series. One that focuses on lost Pokemon/Pokeballs and finding a Legendary Pokemon that is only Legendary because it is the last of its kind: www.elitefourum.com/t/last-pokemon-of-its-kind-a-pokemon-spin-off-game-series/25852/1
Granted, if they want to remake a 3D Pokemon Crystal. I’m happy with @gengarbrigade 's suggestion.
