I was so impressed by the preview of Mindjammer that I went to their company website and pre-ordered the hardback. I was sent the 'thoughtcast' pdf and promptly started reading.
Mindjammer's writing is outstanding. The book is very nicely illustrated and the science is cutting edge. I have read all of the recent RPGs dealing with trans and post humanism (Transhuman Space, Eclipse Phase and Nova Praxis) and this is the one that will make the fans of space opera and the fans of realistic SF very happy. The system used is the FATE engine which is perhaps the best modern RPG for both telling stories and resolving action tasks.
If I were to have any criticism of Mindjammer, it would be with some of the organization of the chapters. There are places where I wish the book had continued with a particular subject (skills for example) rather than placing it in a separate chapter. I feel that character creation should be one long process rather than an outline followed by chapters dealing with the separate sections.
I heartily recommend Mindjammer to anyone interested in realistic, transhuman gaming. You won't be disappointed.
