>>34573990I would say that there's a definite progression within Pokemon, with creatures of a certain level in particular routes on your way to the gym or boss or whatever in each location.
The immediate problem is going into an area where Pokemon are a lot higher leveled than you are. You could dynamically adjust the wild Pokemon levels as you progress but that doesn't really make a lot of sense. Like why would you only be able to catch Pokemon of your own level in a particular area?
Devil's advocate: it doesn't really make a whole lot of sense that all the 50+ Pokemon are on (say) Poni Island either.
You could make it work, and try to shoehorn it in somehow. Personally I'm opposed just because games like Zelda annoy me with how I'm wandering through the overworld much of the time.
