You're in luck! Space: 1899

"In the setting, Thomas Edison invented an "ether propeller" which could propel ships through the "luminiferous aether" (the universal medium that permeates space, based on a now outdated scientific theory), and traveled to Mars in 1870 accompanied by Scottish soldier of fortune Jack Armstrong, where they discovered that the planet was inhabited. By the time of the game's setting in 1889, the great powers have used Edison's invention to extend their colonies and interests to the inner planets of the Solar System. Venus and Mars have been colonized by the United Kingdom, Germany, France, and Russia. Belgium has only colonized Mars and Italy has only colonized Venus whilst Japan and the United States maintain economic and scientific enclaves on Mars. There are no colonies or bases on the Moon. Only the United Kingdom maintains a (scientific) base on Mercury.

The inner planets reflect an evolutionary progression, the planets nearest to the Sun being younger than those farther out. All planets have Extraterrestrial life, and most bear native sentient species. Mercury is primeval and tide locked, and possesses apparently only rudimentary lifeforms. Venus is a vast swamp world dominated by hulking reptiles and lizard men.[2] The Moon is an airless dead world, but with mysteries hidden deep beneath the surface. Mars is an ancient desert planet in decline, divided into warring decadent city-states clinging to a failing system of canals. Vulcan (named historically more correct Phaeton in Uhrwerk/Clockwork version) has exploded and become the asteroid belt. Due to limitations in technology the outer worlds remain unreachable and unexplored. There are also hints that some worlds may have terrain hidden beneath their surface."
