There are several problems with removing auto-saves, or the possibility to save manually.
1. If the game crashes you have just lost a LOT of gaming
2. If life comes and get you mid game, you cannot save and exit as you wish.
I save a lot (crashes do happen), but I NEVER go back if I have made a wrong tactical move or whatnot. I restart the game if I loose, I dont go back to before my failed attack on a troll. Let the players choose themselves how they play.
