Could some of us be gym leaders?
Would legendary encounters occur like the games, basically after the seventh or eighth gyms?

Could a gym have more than one type of pokemon?  Examples in the games (rain helps thunder hit everytime), I don't know if that kind of thing like: "hit everytime would be overpowered in a roleplay sense."

Would weather be in the story, like one day a blizzard hits and our characters could not go anywhere.  Could events or natural disasters like that happen?
