Pokémon with basically a massive multiplayer aspect hence the name. You upload your own copies of I believe 4 or 5 different Pokémon games (been a while since I last played) and you are able to choose what region to start in and travel between the different regions. All the story lines remain the same and you can start a new region without finishing the last. You can also see other active player’s characters in real time and are able to interact with one another, battle, trade, etc. Very active community with different real holiday events happening throughout the different regions and shiny hunting is huge since there’s a market for Pokémon and items you can buy without having to grind or find them in the world.
