Ys 3 (Any version before its remake take your pick). I am just give a preview from just playing the 1ST level. You quite literally die in just a few seconds of touch a single enemy of the dungeon, that experience don't get any better from there because enemies will shred your health in seconds. You need to grind for literal hours just given enough health to survive the first boss encounter.
Ikari Warriors (on NES) prepare to feel like your mind to erode because the movement is slow, the controls are slow compared to the arcade version, you die in one hit so prepare to spam ABBA for over a million times, you listen to the same looping tune for what feels like hours on end, and the levels are slow.
Annet Returns | Anett Futatabi (Sega CD) - The worst of the Ernest Evans trilogy (El Vento and Erernst Evens being the other two parts) It's a beat-em up compared to the other two platformer. It is not a good beat-em up. The movement can feel sluggish, and attacks don’t always register cleanly. Some foes hit too hard or attack in unfair waves, turning sections into button-mashing survival rather than skill-based combat. The game can be beaten relatively quickly once you learn enemy patterns. Outside of spell usage and a few boss encounters, the combat doesn’t evolve much. Most bosses get glitched and the hit boxes aare garbage.
Shinning Wisdom - For One Reason, MASHING B Button to gain speed. It is so bad that I put the game down because it hurt my fingers just constantly mashing that button. Another part is that it took Zelda's issues of constantly switching items all of the time and makes it even worst than any of those games by country mile as it doesn't uses all of the buttons on the Saturn pad. Also cryptitic as hell as nothing in this game would even give a hint on where to go next at certain points. Meaning that you're going to spend a long time wankering around like a moron looking for the next point in the game because existance is pain.
