Gaming

There are many games that would be ruined if that happened.

Probably, but I don't think I'm playing any of them

 Skyrim already has a quick save 

Exactly. As should all good and sensible games.

I don't remember if Sensible Soccer had a quick save 

Sports games aren't sensible. Nobody likes sports

Well put!
*smug*

Don't know about souls-like, but the souls games themselves constantly save automatically and you can quit to the menu at any time, even during a boss fight you can quit and it will plop you outside the boss room when you reload.

I think the saving system should be down to the individual game and what it's trying to do. As I said, a number of games would be completely ruined with the ability to save at any time. Horror games like the original Resident Evils, Dead Space, and Alien Isolation would all be worse off with the ability to quick save as any tension would be completely removed with a casual tap of F5 every five seconds. Part of the gameplay in the Resident Evil games was the risk/reward aspect of deciding whether to keep hold of a ribbon for later, or use it in the typewriter you just found, and not knowing when you would be likely to find another. One of the most intense experiences I've ever had playing a game would be Dead Space 2 on hardcore mode* where you are restricted to a maximum of 3 saves for the entire playthrough. This was far more nerve-wracking than Dead Space 3's hardcore mode which allowed you to save any time along with automatic checkpoint saving, even though that was permadeath and deleted your save at the moment of death.

Not to mention multiplayer games (that's it, I'm not mentioning them).

*Dead Space 2 hardcore mode is the reason I have occasionally joked about the XBox being easy mode. Because the XBox had to swap discs half way through the game, they got an additional save point at the disc swap effectively making the game easier.
