Majora's Mask - don't get me wrong. The story is wonderful, Link falls into a parallel world/timeline that features really screwed up motifs? Yeah, pretty fun, but the resetting timeline makes me fearful and paranoid and I hate time limits on games that feature exploring dungeons and things.
The original 8 bit Final Fantasy/Dragon Quest/Dragon Warriors. Seriously, they are clunky and clumsy and I just want to flail until they go away. I understand that people programmed these when 8 bit computers were a thing, and limited processing power. But clunky menus just make me want to die. (Also, I am reminded of telnet rpgs from back in the day, but those had a little more charm to them...)
Every modern FPS. Limited weapons/ammo, and regenerating health? Yeah, kind of boring. Plus add to the mix of generic racist bullshit (it's always the US versus some country that doesn't speak English), and it's just really not to my taste. Doom/Mass Effect are different because sci-fi and better creativity...
Killer Instinct. It always felt like it was an "off-brand"/"knock-off" from Street Fighter and Mortal Kombat. Generic characters - let's see - a ninja, a scantily clad female ninja, a flame dude, an ice dude, a killer robot, a werewolf and a Native American stereotype. Well, MK wasn't much better - different coloured ninjas were a trademark of theirs. I loved watching the games in the arcades although.
Castlevania - my first game on the Gameboy, and it was Castlevania Adventures with blocky movement and stupid jumping controls. To this day, I can't finish it because I constantly fought with the controls. I find the originals slightly better - although the best of the best is Super Castlevania 4, or any of the GBA ones....
