I would ask more information about some practical implications of this feature. While I am quite positive on the no-turning back-one-save-game play style, it does bring two serious problems with it as well.
1. Autosave - will this game mode have autosave, the main game killer in most scenarios will not be the Ottomans, the Spanish, the French or the Aztec super power empire but crash to desktop, something that is bound to happen quite a number of times between the start and end of game, and losing progress can cause serious loss of willpower to continue a campaign if you have to replay last 30-50 years or so all over again. I have caught a detail in the manual that save is done after each decision, but the hardware-bandwith issues this would bring up make this seem a little exeraggerated, since an average savegame in paradox titles is like 10-20Mb.
2. Save game corruption - the further you go the more likely it is to happen. Will the game make some backup copies to at least return to some previous stage instead of killing the campaign alltogether?
