I've never understood Hard SF.
No FLT Travel, No Jumps through Hyper Space, no HyperSpace, no weird alien species, no immortals, no Psionics, just slowly moving through space to some asteroid or acelerating for months until you reach near-light sped, decelerating until you reach a planet, then going home the same way to find that your baby's grandchildren have grown old and died.
Not my idea of fun, to be honest.
But, there again, I liked Car Wars
