Design Diary 01: The Tannhauser Gates universe

Tannhauser Gates is a Sci Fi RPG Top Bottom Space Shooter ( SFRPGTBSS ) It is  directly inspired by the old space flight simulators game genre like Starflight or Elite, but lets simply call it "TG" for now on.
The Tittle is obviously inspired by  famous Roy Batty  death quote in the end of Blade Runner. ( sorry for the ones spoiled here ;) the quote is: "I've seen things you people wouldn't believe. Attack ships on fire off the shoulder of Orion; I watched C-beams glitter in the dark near the Tannhauser gate. All those moments will be lost in time like tears in rain."
That quote really made us wonder for years what those famous battles would actually look like, and what the Tannhauser Gate was.
 In TG, one of the gates have been found. Ancient relic of a long lost civilisation, scattered in the galaxy. what was their use? are there other artefacts? no one knows.
The gates dont play a center role right now in the game anyways, but there is certainly mystery in TG.
 A whole galaxy to explore.
Umans are the closest thing you'll find  to our earthling standards. And there are many other races: the Brutos, Eluwans, Wargans, Slogs and Xerrs. That's for the known "civilised" races,we'll present them in details to you later. By civilised of course we mean: "able to fly ships and shoot at you" for starters.
But there is more!
Space is a big, cold and scary a place. Spaceships won't be only deadly thing you'll encounter up there.

Will you dare enter the world of TG?
