The Expanse Kickstarter
I am also participating in the KS above, as not only am I enjoying the show on Amazon Prime (and yes, I did dish out $20 to see Season 3), but I see it as a good resource for me as a GM of what a "near future" human only SF-FI setting could look like. The technology of moving in space without any "high tech" or "FTL drives", the lag in communications, the vastness/emptiness of space, the "submarine warfare" style of deadly naval combat (no force-field/shield, or energy weapons tech; stealth + detection + first strike condsiderations), the way commerce works, life in space, and the shear ruthless politics between Earth, Mars and the Belt/Outer Planets is a source of lot of RPG inspiration for me.
For those who haven't seen the show I highly recommend it, but please don't post an spoilers for others. I have yet to read the books, but I will do so very soon.The Expanse, and Why You Should be Watching It. - Spacedock Short
Also, I must give a shout out to excellent YouTube channel Spacedock The Expanse Playlist
for an incredible look at the Vehicles, techs and space stations of the TV show. Well worth watching, but again, it does have some spoilers.
