Master of Magic was one of my favourite games ever. It wasn't balanced too well, but I never cared! The game was so full of content, you could build and do so much! It was a very innovative, but also quite straightforward game.
I actually spent a looooong time with Dioxine designing a "MoM 2.0", which kind of tells how important it was for us - but mostly me, I think.
And thanks for the link, Clownagent!
