I mean think about it....a 3D Pokemon world with trainers and Pokemon running around .it could start off with you and 5 billion other trainers go and get your starter Pokemon from any of the 5 regions. You go around catching Pokemon,battling trainers from around the world(and some NPCs), earn Gym badges,etc. Then ever so often the Pokemon League shows up and you get to compete with others to see who's the best of the best. You could form clans and have clan batttles. For Example: Clan Fire Red Vs Clan Leaf Green. You could go and visit other regions by either getting on a ship,flying there with a Pokemon, or using a water type Pokemon to swim over there. You could go on quests to earn money and prizes(and sometimes rare Pokemon). I would pay monthly for a game like that.
