Ok i dont want to be rude here but im sure some ppl will be .
the point is...... actually theres not point, just like developing another game , is so "easy" and then we make the changes in server for the this new episode.
but tbh , there's easy things to do. (not saying the first option is not easy , ore possible) like better create a history with quests, then developing a game, ore finish unifinishing things in server like challenge and more stuff.
any way good luck , you will need it , cuz what you want is almost impossible.
and topic moved to off topic.
