In my experience, do-overs aren’t all that common in RPGs. Most groups I’ve gamed with (on both sides of the screen) prefer to compensate for mistakes (“Okay, since I boosted the minotaur’s AC, you get double XP”) or treat them as water under the bridge.

One of the terrible Diablo-to-D&D products, however, took things several steps further — players could declare that they were saving the game at any point, and return to that point later on. I don’t see that working terribly well in most RPGs, but it was a decent idea for that particular game.

So with the two extremes being “no do-overs, ever” and “save at will,” what has your experience been? Does your group fall closer to one end of that spectrum than the other, or do you rewind on a case-by-case basis?
