I will be starting a new PBeM pulp SF game using War Rocket, and Fantastic Worlds for space and ground combat, in a society based on Jack Williamsons Legion of Space and Poul Anderson's Flandry of Terra, using the En Garde rules. The rules sets compliment each other quite well. The start date is Sept. 15 and you can join it here
