The one I'm probably saddest about is Ultima VII: The Black Gate. I loved that game when I first played it, but I could never finish it due to a glitch where I couldn't get the door to the final boss fight open. That was years and years and years ago when I needed a boot disk to get the game to work. I've since got the game again on GOG, but I haven't gotten around to finishing it yet.
Fallout 2 was another one - I ground through the original Fallout to completion, but the second game just defeated me.
And back in the console days pretty much every game I played fell into this category - I never finished any Wonderboy game, for example. I never finished Resident Evil. I never finished even one season on F1:'97 on Playstation (or F1:2010 on PC, for that matter
)
