My biggest complaint with LG P/E is how much they butchered from the previous games. Pokemon didn't have abilities, relied too much on a dumb catch mechanic, and items weren't spectacular either iirc. It was, at best, a spin-off masquerading as a core series game. Never played Gen 8, but Gens 2 through 6 were solid on their own. Gen 1 isn't that good but I can't hold it accountable for that considering its time. I also never played B2/W2 or the original S/M either so I don't have an opinion on them.
