What game did you not want to finish?

Of all the games we've played, there are always a few that we're so immersed in that we don't even bother to follow the main story.

For me, one of the games I've been most reluctant to complete in recent years is Red Dead Redemption 2. Arthur's asthma gets worse as the game progresses, and the occasional cough is painful. I don't want to see Arthur die of illness at the end of the game.

So, of all the games you've played, what is the most difficult one to beat? Let us know in the comments section!
