I have a list.
Yakuza 3, the long scenes of dialog kind of diminish my desire to play.
Fallout New Vegas, only being capable of doing one path at a time REALLY messes with my OCD.
Skyrim, taking my time but have generally the same problem as Fallout New Vegas.
Kid Chameleon, 103 levels is insane for a game from 1992 on the Genesis and they get confusing.
Streets Of Rage 1-3
Golden Axe 1-2
Sonic, Sonic 2, Sonic 3, Sonic & Knuckles, Sonic Spinball, and Sonic 3D Blast.
Alien Storm
Alien Syndrome
Gain Ground, I get pretty far but I get stuck on the same level which seems impossible.
Odin Sphere
GrimGrimoire
There's more, but I'll save myself the embarrassment lol.
