honestly, if you were to have a game that let you go to any region. I think the number one thing they should do, is make it you can start in which ever reason you choose. There really wouldn't be much of a reason against that unless they were trying to balance it to be a super long term game, where you sort of reach level 100 or so around the final region. That kind of a game would be really cool in theory, until you realize just how slow your team would have to level in order to balance it.
