>>35922565I think it was a bit too overambitious. You ended up with a lot of mons that felt redundant with things they had to substitute because they were from a previous game.
I think they could have included some mons from previous gens that people don't often get the chance to use at all while still keeping things feeling fresh. Having Pichu as an rare encounter early on, for example. Not something people often use for the main game, and lets them slip in their mascot.
150 mons has never really been enough to flesh out a region with.
