I think this is a concept that would evolve the series, not end it. For years its been the same thing again and again, each game only differing in graphics, new pokemon, and a new location, with the exception of new gear some of the time. Why not a fully realized rpg with multiple regions, and open world? It wouldnt even need to be in first person, 3d or anything. Just put in on pc and have one base game capable of adding expansions, with the option of both single play and campaign, not just trade and battle, but multiple players completing quests together.
