>>23102716>Enemy AI was smarterPokemon's AI was notoriously shit, and movesets were terrible in the older games. Even in R/S you had shit like Solarbeam Aggron. You're deluding yourself if you think it was any better.
And obscuring move effects or items doesn't make the game harder, it just makes it annoying. Might as well make the entire screen black, because graphics let you see what you're doing and makes the game too easy. You could also easily trade shit to each other to breeze through the game, that shit has existed forever. Multi-use TMs were rarely a big deal since most teams only had 1-2 Pokemon that could learn a specific move, and so many dumb kids just steamrolled through the game with one Pokemon anyways. Super Training really only makes EVs less of a grind, you could still abuse them it just took more work. Poison outside of battle was neat, but burns have never bothered you out of battle so I know you're just running on nostalgia fumes.
1 time legendaries or fewer shinies don't have anything to do with making the game harder.
