Transhuman Space
A hard science RPG set in the year 2100, Transhuman Space bills itself as 'a realistic speculation on the future'. There are no aliens or warp drives, and most of the action takes place within our solar system. It serves as a showcase for Transhumanist ideas, and covers a period when the human race is diverging into a clade, or cluster of related species through genetic engineering, AI, and nanotechnology.
