>>57777133New Snap and Pokkén DX are the only good ones.
LGPE and Mystery Dungeon Rescue Team DX are okay, might be better off with FRLG and Mystery Dungeon Rescue Team Red or Blue.
PLA is subpar, but if you can get it for a decent discounted price and like catching Pokémon, you might get some fun out of it.
BDSP is not worth playing over Platinum, but it isn't the worst Pokémon game on Switch.
Detective Pikachu Returns is too padded and boring even if you were a fan of the 3DS original.
SWSH and SV are horrendous, the worst Pokémon games out there. Barely adds anything meaningful compared to past entries. They're also overpriced and you're seriously better off spending that money on the plethora of other games on Switch.
The rest are freemium mobile slop.
