As I’ve been looking over everyone’s ideas I cant remember if anyone has mentioned grouping. Like two person groups or something like that... that way if two people have the same quest (mission, whatever) they can do it together. Then there might be a way to make a battle two on two or two on one. (Depending on if it is with a wild pokemon) one player controls one of his pokemon and the other player controls his. It’s also a great way to level up. If there is someone with low-level pokemon and they group with someone with "higher up the food chain" pokemon he can be leveled up faster. If I’m wrong and all this sounds like psychobabble, or someone already posted something on this topic please disregard this.
 Thank you.
