I've been playing this for a while and it has taken the classic Master of Magic and ironed out all the issues and added a huge amount of content on top. There are massive improvements to the spell lists, race balance, traits, game concepts, diplomacy and AI, not to mention fixes for loads of bugs and broken features. Yes it removes some of the old favourite broken strategies like 10 book starts that basically win the game for you which were quite fun, but it has added so many more interesting and varied strategies. I must have played this for 250 hours already, it's simply the definitive version of one of the best games ever.
