Sometimes I have played with a thought that if roleplaying games had a save game feature. Kinda like fate (or-what-ever) points you earn as a group and can use to save game. Then you can kick-in-the-door approach, see what's beneath, die and "load game" for a better approach (for example).
Or before epic battle you use save game. Just because if the dice screw the epic battle (TPK) you can re-try it.
Just an idea I have had sometimes when I play video games. But what do you think?
