I have seen a lot of love for the Traveller #rpg recently. It is a great time to be playing that game as there are a multitude of free resources. Thready thread.
There are multiple free versions from @StellagamaPub from Cepheus to C Lite, to C Faster Than Light, to Quantum https://www.drivethrurpg.com/browse/pub/9571/Stellagama-Publishing?term=stella. Yes Mongoose based but easy to approximate classic.
Tons of free geomorphs all over the place but this free supplement alone will set you up forever https://travellerrpgblog.blogspot.com/2018/10/the-starship-geomorphs-book-if-finally.html
Years and years worth of free zine material here https://www.freelancetraveller.com/magazine/ and here https://cepheusjournal.com/downloads/
Amazing "official" map site https://travellermap.com/?p=149.621!-107.108!0.95
Finally, amazing generators for subsectors https://campaignwiki.org/traveller/edit/ and characters https://devilghost.com/software/travellercharacter/. There are also too many Traveller blogs to name.
Thank you to the creators for all of that stuff, I am just the lowly messenger. That is way more than you will ever need to play Traveller for free forever.
