Good Steampunk PC games
Rise of Nations: Rise of Legends — With one of its three races (the Vinci) heavily relying on gunpowder and clockwork, the fantastical successor to the historical Rise of Nations falls neatly into the Steampunk genre. As befitting a magic-and-tech game, Rise of Legends sports a magical civilization called the Alin, as well as the alien race of the Cuotl.
Arcanum: Of Steamworks and Magick Obscura — The game’s title says it all, doesnt it? For yours truly, Arcanum is the best Steampunk computer game built to this day, not only because it is brazenly Steampunk, but also because it is one of finest (if underrated) game worlds, ever.
Final Fantasy — But of course! Square’s paramount franchise has been long-known to mix the fantastic with the scientific — magic spells, airships, Guardian Forces, spaceships.
