Re: Main storyline with Unova Pokemon only - good idea?
I was reminded of the time I started playing R/B in the first generation. The "oh hey, something appeared! I wonder what it does?" scenario- that uncertain and adventurous feeling- was constantly maintained throughout the game. I also noticed that this time they didn't litter the entire region with a bunch of commons and designate a few different rares in each location. Instead, they designated each Pokemon to only one or two locations in the entire region and always updated the roster for wilds, keeping something new for every next route. Except for Audino, but everyone loves to beat the stuffing out of it anyway.
