Blue Planet has been one of my favorite SciFi RPGs ever since it was published.
The second edition is brilliant, plays nice and quick and throws a huge amount of campaign ideas at the GM. The only thing for me was, that I was yarning for more input, maps, descriptions of paces, adventure ideas (which, I must admit, are not so easy to find in a hard sci fi environment, at least if you are neither a geologist nor zoologist - I would not have come up with the Tiger Rocks described in one of the adventures).
Having skimmed through Blue Planet Recontact, it explicitly picks up where the second edition left. Rules streamlining (which you might like or not, would have to playtest this, but the first impression looks fresh, very modern and playable), adventure and campaign ideas. I am really excited about is the authors' idea about eight campain archetypes to help GMs start new games. This reminds me of Coriolis' brilliant idea which seems to have been picked up by this crew.
I am quite excited to see the finished product released and hope that Blue Planet will (once again) resurface from the dark deep blue for a bright future.
