Re: Do you play in Ironman mode?
My view is similar to PikeStance's. I agree with the idea of not reloading after a defeat simply because you lost and want to win. I enjoy campaigns in which I need to recover from the occasional setback. I think there's a difference between, for example, reloading to roll the dice again (with an auto-resolved battle) and reloading to replay a battle manually (after being defeated when playing the battle manually the first time) to see if different tactics would have worked better. I enjoy books or TV shows which discuss historical battles or campaigns and consider whether different choices would have led to a different outcome.
Similarly, if I've invested many hours in a campaign and make a strategic error on the campaign map, then I don't have a problem with going back a few turns occasionally to try a different strategy and see if it works better. I wouldn't want to have to re-play the entire campaign each time to reach the same point to test whether a different strategy would work better.
