Passing over this thread a few times, I recalled a game that I never managed to will myself to return to and finish.
Grandia by Game Arts for the Playstation.
I tried to just run through it, but I would get so bored out, can't remember what it was, the music or the story, the characters and the voice-acting, etc... But yeah, I tried a handful of times to continue off from my save point, but would eventually get tired and put it off for another day - the last time was 7 years ago I think... Then there's the problem of waiting too long and completely forgetting the story, what the hell you were supposed to do next, and realizing you're probably better off starting over and attempting to get through it in a timely fashion without long breaks...
I used to have a personal policy that if I bought a game and started playing it, I will finish it to the end, even if it's lousy... Grandia remains a thorn in my side relative to that policy, it continues to remain unbeaten and I kinda dread ever going back to it.
