... well, there's Age of Wonders. But really Master of Magic is unique in the scale of the magic you can cast in a 4X campaign. The remake left me dissatisfied, but to be fair the original is also very rough in some parts -- definitely install mods. My favorite is Caster of Magic for Windows (which is a separate purchase on GoG).
This is more of a remake of Master of Magic than a mod. Among the changes: 14 wizards, options for truly massive worlds, new wizard powers, new spells, building queues in towns, new AI, new ruin mechanics, new treasures... I'm rather disappointed in Slitherine for selling it as if it were a mod and requiring a purchase of Master of Magic, because it is, in fact, a stand-alone game built from scratch. I thought Slitherine was a pro-gamer company but... apparently not. Their launcher is also absolutely awful. Slitherine's sins aside, I'm really impressed with all the changes and enjoying the game so far. Yay for rebirths of favorite old games!
