I'm almost tempted by this feature but I didn't vote because I feel that Jade should stop the Adom paranoia against players. It penalize only standard players, those that save scum will anyway have plenty backup and won't care.
So instead of a complicate backup, just a game that can be saved without to quit, if people want cheat they'll do it anyway so no reason to penalize other players because of an excessive paranoia. If you feel I'm rude, think again and don't forget that the Adom game has been rude with me by making me lost days of play just because of a paranoiac design. Yeah free game, I know, as is my play... sarcasm here!
