Gut Check is a set of free wargames rules for 15mm science fiction battles. What makes it unique, I think, is that it’s designed from the start for solo play. The author lists its features:
Designed from the ground up for solo play
Fast playing and zero bookkeeping
Uses normal 6 sided dice (Usually rolled no more than 2 at a time)
Uses activation rolls modified by battlefield conditions for turn sequence
Seamless Over watch and suppression effects built into system
Use any miniatures
Played on a Hex grid for convenience, but could be played with little fuss on a standard table

Dune Express is a print-and-play board game based on the 1970s era Avalon Hill game Dune. The authors write:
DUNE Express is a print-and-play boardgame. It is based on a game published in the late 70s, which was set in the well known science fiction universe created by Frank Herbert. The original game was quite complicated. DUNE Express is a community-written version of this game which is much more simple and quicker to play (hence the “express”). I chose to take these Express rules and create all the components for the game as a portfolio piece. I was keen to give it a Steampunk theme and to avoid it looking too technologically advanced.
