This is a common occurrence for me since I don’t have much time to play. I often get about halfway through and then stop playing for months. When I come back to it I always want to start from the beginning and then the cycle happens again.
One example for me is Fallout 4
Shadow of Mordor and Dying Light 1.
I’ve started both about 4/5 times and just really struggle to get into them. Really want to finish them though as I was to play their sequels as well.
