Glad to see Castlevania on that list, that game was brutal on little me as a little kid.
But let’s get real, there is a long tradition of brutally hard games, and people be bullshitting if they say they beat some of these games without save states 🤣
Let’s also talk about arcade games that are brutal even with unlimited coins - R-Type, Pulstar, ghouls and ghosts, just to name a few. But these are all beatable.
A NES game that I thought was exceptionally hard without save states (looking at you doungen with no lights and hard enemies) is NES Zelda romhack Outlands
