Magitech

Magitech is a setting published by TSR in 1993 for use with the Amazing Engine and was an attempt to have an Earth that had magic and other races since the beginning.
Despite the high historical inertia there are key differences:
* c900 CE: Space travel was developed resulting in colonies of Venus (Hanahpu) and Mars with ruins going back 1000 years. There are rumors of an outpost on Titan and further out into the solar system
* Mayas of Central America disappeared for 500 years (1000 to 1500 CE) and yet were able to pick right where they left off
* The Mayas were able to curtail the expansion of the United States west of the Mississippi River
*The Republic of Texas is ruled by Minotaurs
*Lizard men are the Khmer people
*The Dwarves are the Germans and yes their attempts at empire building triggered off World Wars I and II here as well. Nothing about their second attempt resulting in a Holocaust though.
*Electricity as a power source doesn't exist. Neither does petroleum.
*Gunpowder doesn't exist
==Comments==
About every issue outlined in Bright: The Apotheosis of Lazy Worldbuilding also applies to this setting.
Also the comment "When magic can do things more simply and more cleanly, why would anyone use technology?" shows a total ignorance of Niven's law: "Any sufficiently advanced magic is indistinguishable from technology." That existed at least as far back part 2 of the serial Battlefield from season 26 of Doctor Who, first aired September 13, 1989. In a case oblivious irony the author answers this very question when they state there are several elements magic cannot affect directly, among them iron.
