In the old days you could just exit out to the pause menu or save so you could go to the toilet or answer the phone or talk to your family and your in-game activities were safe. You could pick and chose when and how you wanted to play.
Now you cant stop when you want, because if you do you'll just be left "idle" in-game. This means that you're prey for other players or NPCs in game, and you risk losing your character's progress and you're back to the start (sometimes there is a significant time-investment to this progress so understandably you dont want to risk it). You can only stop when you get to some sort of safe-place in-game, which means you have to play longer than you want to.
So you get situations like where if I am playing a game and my wife asks me to come and see something or make a cup of tea or something, I have to ask her to wait until it is "safe" for me to stop. I feel like I am prioritising the game over my wife (and I guess I am to an extent).
I dont like this.
I really wish games would allow you to just quit whenever you want without risking your in-game progress.
