Far Trek is an RPG set in the Star Trek Universe. It’s one I’d love to play.
There are also paper figures for away teams and aliens.
Science Fiction
Mass Effect Tabletop RPG
The Mass Effect RPG is an homage to Bioware’s first person science fiction shooter of the same name.
It’s a well done product, and if it interests you, download it before Bioware’s lawyers get ahold of it.
Warband Science Fantasy Role Playing
Warband is a free RPG with a science fantasy, science fiction flavor. In truth, it could very well be the Warhammer 40K RPG. The author writes:
This game is my homage to the ‘grim, dark future’. A game of spikey power armor wearing, bolt-gun shooting, chain-sword waving chaos worshippers. Characters struggle to survive in the warp of space, as low-level members of a Chaos Lord’s warband, they strive to make a name for themselves and eventually captain a ship of their own.
Modeling Alien Trees
Dropship Horizon has a good idea for turning pine cones into weird looking alien trees.
Hitchhiker’s Quest For The Galaxy Game
Hitchhiker’s Quest For The Galaxy is a home-brew card game based on the book of the same name.
You gotta love a game which specifies that “the most depressed player goes first.”
