I agree with `rickah88` , HoMM3 is great game. I like unofficial expansion Wog, that was created by some Rusian team ( they really love turn based games
Great idea for individual exp for units which made us to play carefully and perserve our army, but allas it was full of bugs.
There are so much custom made maps, and all of them can be played differently but for me most fun in HoMM3 was in Hot seat/Lan with some friends. That`s why i would love for KB2 to have some kind of multiplayer option, untill then were just wishfully adding to this list
