>>57899714 (OP)hiya! zoomer here who has played these 3 games:
scarlet/violet are very buggy and had a lackluster open world with some washed out visuals. they're not bad games per-se, they're just more story-focused than gameplay-focused.
pokemon sword/shield are primarily review-bombed for being the games that introduced "the dexit." where they removed the ability to have every pokemon from the mainline games, but a lot of people just didn't like how they played, alongside their graphics.
BDSP are legitimately just a buggier, chibified version of the original diamond and pearl but with faster battles, a competitively viable cynthia team, lower difficulty before the elite four, and no HMs.
all of these games are still good games, but they're not exactly "the favoured games" unlike the stuff that came before them.
they're all worth playing, but I wouldn't suggest buying them for over $45.
