Sons of Heaven
I just picked up the recently released Sons of Heaven Sci Fi RPG.
It is by RPGPundit, who puts out some great OSR related content!
The engine is heavily based on B/X (yay) and is very similar to RPGPundit's Star Adventurer RPG. This is a great product; I have ordered the hardback while I dig through the PDF.
A very cool setting, that you can use, adjust or ignore however you choose. Some great tables, the setting seems to be heavily based around humans, BUT there are some great alien species in the setting (based on classic aliens from legend, yeah Greys are in there!), plus you can make up your own! Thats a win! Great random generators in the book. Overall, I think the setting has a very Firefly, Bronze age in space feel to it, which I love! Now if I can just lure some folks away from 5.5 (shudder) to try it out! The art is AI, but it is very well done and captures the setting. If you are an anti-AI art person then this isn't the book for you.
Here is the elevator pitch I worked up for my potential players. Hopefully more to come on this awesome game! I think this is the OSR Sci Fi game I have been waiting on for a long time!
