Fallout 4. I just stopped for some reason. I think I was close to having to pick one of the factions to support and I couldn’t decide, then got distracted by other games. I tried to pick it up again recently and didn’t remember the story. I’d love to sit through and read summaries of all the quests I completed so I can catch up on where I was and what I did one day, and then I can finally properly finish it.
