Im kinda forced to access them, otherwise I limit myself on what Pokemon I can catch. Sure I could trade with other players to find what I want, but I would miss out on TMs and other story line items by NOT doing it, so that really isn't an option.
Sure but pokemon belong to their respective regions. I mean, we can put some of them into different regions, but we can't do them all. That would be overcrowded as hell.
Blame handhelds for that.
