most of the shit i can think of are disgaea achievements
disgaea 2 - spent 300 hours on it and got super gimped with triple super robo suits probably maxed out on stats (as high as possible) as well
disgaea 3 - there was a glitch where you can use the puppy paw stick thing to steal a magichanged weapon from an enemy, and i can't even remember how many fucking hours i spent resetting just to find the right unit AND pull it off
disgaea 4 - won't lie, just getting the flonne robot parts was a fucking piece of shit, i even made a video long ago capturing the moment where i beat the last pirates and obtained the last piece cos they just would NOT appear, fucking rng assery at play
sadly i was never able to beat Baal in 5 6 and 7 cos i just couldn't be bothered to grind mindlessly for it, even though i know there were "smart" ways to do it than the "hard" way
i guess one of my earliest big achievements was 100%ing
ratchet & clank going commando without looking up a walkthrough, even finding the last nanotech which was in a spaceship mission
i wouldn't count my pokemon blue missing no. item dupe an achievement cos i just learned about it from someone and made the game way too easy, but i gotta say at the time, i felt like a fucking GOD with 99 masterballs and shit
