Following on from yesterday's post I've been doing some thinking about hard SF. In principle I like the idea, you see. It's just that it's all so bloody difficult if you're a non-scientist like me. (My three GCSE Grade B's in Physics, Biology and Chemistry don't exactly stand me in good stead. What I really need to do is take a degree in Astronomy or something.)
There's also that old chestnut, the Player Investment Problem, or as I sometime think of it, the "a-realistic-game-set-in-ancient-Babylon-would-be-really-cool, but-only-1%-of-gamers-would-invest-anything-like-the-necessary-time-to-make-such-a-game-a-success problem." Which is to say, Pendragon and Harn are tough enough sells to most players. Don't even talk about a game in which you have to deal with lagrangian points and parsecs.
Transhuman Space looks interesting, were it not for the fact that I find the idea of transhumanism kind of laughable and revolting at the same time. It may be worth investigating to see if I can excise that part of it completely. Then again, that really probably just boils down to a very hard SF version of GURPS.
