Someone actually said it, yeah especially in open world games I seem to be having that issue. I don't know but maybe it is because of the fact that it is a bit to open...
I am one of those guys that actually don't mind linear games (when done right of course). And I feel weird when people mention games being linear as if that is a bad thing in itself when I don't mind that one bit.
The fact that you only finish games you enjoy and not necessarily good games is a statement I would like to align myself too since games that are really good are not the same as games that I enjoy, games that I enjoy are truly subjective.
One way or another, maybe I am just an old man that never will get back into games the way that I played them. Games, games never change... They just... Ok games have changed a bunch!
