I remember being hugely disappointed playing a HOI2 ARM Russian campaign and crushing the Germans in the spring of 1942 and conquering the whole of Europe and China by late 1943. I could beat the AI opponent hands-down every time on the hardest difficulty settings. But, by this time, I was getting too good at it. I bought HOI 2 when it was released and bought the Armaggedon expansion too.
It had one of the most detailed tech trees I've seen in a game.
In the meantime, I found Hearts of Iron and that looked like it would scratch the WiF itch.
I used to be a big fan of the World in Flames board game and was quite excited back in the late 90's when I heard that they were going to make a computer version of the board game. Is Hearts of Iron 3 completely unrealistic? Didn't seem that bad to me, at least with black ice mod. Why do people seem to prefer overpriced operational games with counters? The interface is lovable and completely understandable. Hearts of Iron 3 is a great game, as far as I'm concerned.
