Master of Magic has been on every PC I've owned as well. And gog.com's version was the first thing I installed on my newest Win10 laptop a few months ago: Runs with no problems :)
This is such a weird coincidence. I've been listening to The History of Rome podcast [1] and was getting the itch to play some civilization/strategy. I literally downloaded Master of Magic from gog.com (had purchased it there years ago) about 20 minutes ago.
Quite a lot of strategy in MOM. In a way, the several unbalanced units, psychopathic AI and diversity of units and spells adds up to quite a compelling and deep game, even by modern standards :)
Archmage + channeler + confusion spam can win so many otherwise unwinnable battles. And yes, I have alechemist to keep up the mana supply, so I have almost no spells or troops and still win fights with my magic spirit scouts.
Naturally I use Rjack's portrait as I'd prefer not to face him in game with a strategy like this.
