March of War may be the fresh approach that will revitalize your interest in the era. The multiplayer strategy game is set in an alternate 1940s timeline when dieselpunk powers war machines fight on the front lines for five factions. It's also episodic, free, and available right now through Steam's early access program.
The game's isometric view puts you in the commander's seat as you fight against other players in a turn-based format. The first episode, World Aflame, is the core game; further episodes will be released on a monthly basis. Steam players who jump in right now will receive a welcome pack with infantry and special command abilities.
March of War will eventually be released on multiple platforms this summer, including PC, Mac, iOS, and Android. We've got the release trailer after the break.
