Been skimming through it. Niceness!
Although I wonder at one thing… the art in the beginning of the book is mostly computer graphics and 3D-models, which is cool! But then suddenly its all back to the more conventional HARP-hand drawn pictures, more or less skilfully done. This change in art changes the tone and impression of the book. Contentwise it doesn't change anything of course, and I like what I read, very much!
I've been away from HARP for a while, testing out a new system (BRP) which is entertaining and rewarding, the system has its endearing characteristics… yet I more and more get the feel for returning to HARP, perhaps mainly since I'm playing in my own setting which was created using HARP…
Now HARP SF gives me the opportunity to play a semi-proper hard sf game (Spacemaster is too much of a hassle for my players it seems). I like it!
