I mean, it’s not a bad idea per se. It’s just that saving non-stop may not be necessary. You could consider a smartish system:
- autosave if no save was done in the last minute
- autosave only if data actually changed
When the player: moves, fiddles with inventory, clicks through dialogue, flips through options - set a dirty flag in the save game system stating that data needs saving. This could start a timer; if no other save happens in the next 60s, autosave now. Clear dirty flags. Any type of saving that you have already set up clears those flags as well.
- pop an autosaving icon to warn the player?
- let them disable autosaving / control how often it happens?
