Big Ideas, Grand Vision and The Final Countdown

[rfmcdonald]

The Swedish transhumanist Anders Sandberg has some interesting roleplaying game settings: Big Ideas, Grand Vision is my favourite if only because of the sentient coral reefs which inhabit the Solar System alongside 26 billion other very alien humans and the Trahan at Lambda Serpenti. It's an exuberant hard-SF romp.

The Final Countdown is a rather darker one, inasmuch as the setting has placed human civilization in a life-and-death struggle against an interesting alien species and any attempt to communicate with them could easily mean the obliteration of humanity.

Just to mention.
