They were bastard-hard games, but I was very fond of the Commandos series. Richly detailed maps to manouevre your squads around and weedle out opportunities for subterfuge (because all-out combat was always a death sentence).
I've not played anything like it for many years.
So I was interested by Shadow Tactics when Mike Bithell called it one of his games of last year:
