>>48995305It uses Pokemon GO catching mechanics instead of battling wild Pokemon. It also is mostly limited to the original Kanto Pokemon.
Which might not seem like bad things to someone outside the franchise, but for many, it's a significant downgrade. There's very little reason to play it if you're already into Pokemon.
To be quite frank, if I was getting a Switch Pokemon game for a little kid, I would go with SWSH or BDSP, as shitty as those games are
