I've been playing Civilization for 25 years and I'll never finish that, version numbers might change mechanics have evolved but I'll never be finished with Civilization. Sure sometimes I take a brake and don't play Civ for 2 years. But I always come back.
Aside from Civ, I usually feel pretty content and just quit, there are quiet a few games that I have to force myself to finish because I feel content before the actual end.
Only game (in the past 20 years at least) that have left me kind of empty was BotW. The feeling I miss is the exploration when the world was new to me. And that game was as above, I mucked around a lot and explored and then I beat Ganon and then mucked around a bit more but just finally felt "done" with the game. I've tried to pick it up again, but the awe of exploring a brave new world simply isn't there any more for me, so I leave it up to the memories of exploring the game initially and a bit sad feeling that it will probably be another 20 years before another game like that appears.
