The company Alien Dungeon, known for their game Fanticide, has announced it's next line, All Quiet on the Martian Front. It's Victorian Steampunk where worlds at war have replaced a world war... for now.
Very intriguing, and the tanks/artillery are fantastic, except the proposed scale is 15mm. However, any alt-history game that has Teddy Roosevelt as president during 1912 earns a proper look-see.
