CMV: There is no reason why PC games can't have unlimited save slots

In many of the games I played, one can create a folder, move all of one's saves there and then all the save slots would be free for use again. No game I tried, however, lets you actually do this simple file manipulation from within the game, and no game does it for you automatically when saving. 

There are games that restrict save slots to one for valid gameplay reasons, which is fine, and "shitty PC port" could explain this decision in some other games, but I've even seen PC-exclusive games do this (kingdoms of amalur is the most recent example that comes to mind). Why? If there are memory concerns, I'm perfectly fine with not having all the saves accessible at once but I don't see any valid reasons why this would be simply impossible to do within a game.

CMV, reddit.

Some PC games do offer unlimited saves. The Civilization series is the first to pop to mind. The limited saves isn't usually due to restraints in memory. It is usually for strategy. Unlimited saves reduces your risks.   

I remember the old days of PC gaming, MS-Dos, Commodore, and the rest. Using hex editors on saves was fun. Definitely unbalancing but fun nevertheless.
