I wish all games would just let you save whenever you want to! Why is using checkpoints and auto saves so common?
At least add a quit and save option if you want to avoid save scumming.
These days I just want to be able to squeeze in some gaming whenever I can even if it’s just quick sessions. That’s annoyingly hard in games that won’t let you save.
If you want to save, you gotta be able to take the current state of everything and serialize it, then read what you’ve serialized and put it back.
If you only do checkpoints, you can make assumptions about game state and serialize less.
Generally, it is much easier to develop AI and such when you never have to pull it’s state out and then restore it, because if that is done improperly you get bugs like the bandits in STALKER forgetting they were chasing you after a quicksave-quickload because their state machine is reset.
With checkpoints, you can usually say “right, enemies before here? Dead or dealt with. Enemies after here? they’re in their default state. Player is at this position in space. Just write down the stats and ignore the rest.”
And autosaves just make it one less menu to fiddle with.

From video gaming to card games and stuff in between, if it’s gaming you can probably discuss it here!

Reason is “Game state is hard”.
