>>43852475I gotta come clean but the fucking Smeargle wiped my shit in regular SM cause it had a grass type attack, the fucker. Other than that the Grass trial can get shitty and of course, Ultra Necrozma.
But, TODAY, the hardest shit to play is regular Red and Blue, the slow speed, the lack of good moves, shit item management, etc... I love those games but it´s a chore, more than hard.
Battle Frontier Emerald is probably the hardest shit, specially places like the fucking battle palace which might as well be fucking 100%
RNG.
Also the final stretch in Colosseum if you wanna catch all pokemon right there can get very fucky along with the skill swapped slaking at the end, but the Infinite Masterball glitch makes it 10x easier.
