We already made our decision on this, as you can read in that thread. Polls aren't going to change our minds.
Too bad, because X-COM had this feature, and I don't see it as cheating, but as something useful. From my experience, I always retry the mission until none from my squad dies.. so it's either luck or more time wasted, and now I'm reffering to those times when you spend 15 mins to hunt the last alien and it slices your best soldier with a kerrblade before getting shot
You can save the game in geoscape, change the game difficulty, increase gamma until night becomes day... so people can chose alot, in order to have the game experience they want.
Not saving during the battles is called ironman mode, and several games had it, including JA2 and Fallout tactics, but they still had a normal mode where you could save.........
