I would like to see another company put out historical supplements, like Avalanche Press. I can stand their tacky covers, but the books are just way too short for the subject. I want 128 page books, mininum on things like Rome, Arthurian England (real or legendary), 3 Kingdoms era China, Ancient Greece, etc.
I'd like to see a semi-realistic, semi-plausible sci-fi game. I like Traveller, but it's not plausible. I like Fading Suns, but it's not realistic.
Maybe something like 2300 AD , only without the French as a major power (Europe, yes. But not France by itself. Bah)
