Why don't you take a look at the
Elite RPG ?
Wow, the off-topic threads are bringing up some nostalgia. Seems to be a lot of 40-50 somethings in the Elite!
Writing an RPG is quite an undertaking so I wish the author luck! I have written my own RPG rules as an inexpensive time-waster over the last 30 years and torn through probably 100,000 words of text, starting literally with pencil and notebook paper notes and drawings before I ever got my first computer. And that includes very little back-story or game-world creation and mostly just rules. This partly because I think every GM should run a somewhat unique RPG world that the players help influence.
I started thinking of a game of one-on-one firefights after going from strategic level WWII war-games to Squad Leader but didn't get any fire to actually design a game mechanic until a neighbor started a D&D game. I had a lot of quibbles with the D&D rules so I just had to do my own- but to no end but my own puttering!
My daughter is almost old enough to start playing a pen-and-paper RPG but they take up so much time I don't know if I will even try to devote it to replace our current hobbies and of course playing Elite Dangerous on the PC under her own account when it is out.

She is a Skyrim and Minecraft girl right now along with the odd Warcraft III co-op game we will play.
Someone mentioned Squad Leader as well in this thread. I spent a lot of hours playing that (and other table-top war-games from Avalon Hill, etc.) with rule books in lap. I have a new neighbor across the street that still has his Squad Leader box and we have talked about cracking it open this summer. Not sure it will be as much fun though, now that computer games are so glitzy and easy to hop on and off. Maybe a relaxed afternoon with some glasses of Jameson . . .
I have lately gotten a bit nostalgic and almost regret parting with the earliest RPG books I had, including the original series of Traveller little black books. I do still having an almost complete collection of Dragon Magazine from #1 to #125 (and I think a few prequel Strategic Reviews as well...) that I have been thinking of putting up on eBay.
I think Traveller and Elite are pretty close except for the back-story, with ship design and hyper-space travel seemingly aligned pretty well (1-tonne of fuel to travel 1 LY with class 1 drive, for example and if I recall correctly. Various tech levels, classes of drives, weapons, etc. possibility to trade as a merchant). Generating star sectors and systems with random dice rolls and bar-code descriptors (Universal World Profiles) was a fun solo pastime for a short while and does seem pretty procedural.
I think the RPG tie-in makes sense, but I also think the video game will be a lot more practical and fun for me as I won't have to put so much time into it either being a GM or finding one and making time for gaming.
Speaking of time, I have to get off the Forums, they are really addictive and have just gotten me amped up for Elite. I can't believe I missed the Kickstarter - I guess it was my newborn son that wouldn't sleep more than 2 hours at a time and kept us up and sleep deprived for over a year ...
