@nyrath There are so many different ways to tackle answering this question. Movies? TV Shows? Comic books? Formative books? IPs? Versions I owned or consumed? Current versions of those things? Here is one way for me to answer what my #scifiDNA is -- these are the editions I first encountered of these products, although in three cases I was already familiar with the source material from other media ;):
A photo of the three well-used rulebooks of classic traveller on a table, fanned out in a spread, partially on top of one another, on a dark surface, with a ruler or meter stick under them to the left showing scale. The books are flat black, with a red line partially across the cover at about 1/3 up from the bottom, with the word 'Traveller' in large red text right justified with that line. Immediately below the word 'Traveller', in smaller white text, are the words 'Science-Fiction Adventure in the Far Future'.  Above the red line, left justified, is medium-sized white text which identifies each volume:  'Book 1 Characters and Combat', 'Book 2 Starships', and 'Book 3 Worlds and Adventures'.

The box cover of the 2nd edition of FASA's Doctor Who roleplaying game -- A painting of a rocky arch with vague mist coming out of it frames the figures of the 4th Doctor, turned slightly away and looking back at the viewer, and his companion Romana, in a cautious crouched pose with a prominent knife.  Above them, a red and yellow rendition of one of the classic Doctor Who logos (I think the 5th Doctor, but I'm not sure).  Above the logo is yellow text just saying 'The' and below more yellow text saying 'Role Playing Game'.  Along the bottom of the box is more yellow text reading 'A game for 3 or more players, age 12 and up'.  In the lower right corner is a yellow FASA logo.

The cover of the box of the FASA Star Trek RPG from the mid-90s -- specifically the 2nd edition cover. It's a color painting of Kirk, Spock, and McCoy with phasers drawn, cut off at the knees by the bottom of the cover. Behind them is a colorful nebula in reds and blues, and over their heads and far behind them is the class TV show Enterprise flying up and to the right, with trails of light coming off it's nacelles and lower hull.  At the top, in bold white text in the same font as the show, are the words 'Star Trek', with the sub-heading in smaller type saying 'The Role Playing Game'.  In the lower left corner is a small white FASA logo.

The cover to the first edition of West End Games Star Wars role playing game. The picture is a painting with Luke centered, holding a blaster pointed directly at the viewer, at whom he is also looking directly.  To his left (our right) and slightly behind is Leia, shooting a blaster off to the right of the picture.  To Luke's right, our left, and also behind and a little lower is Han, likewise shooting a blaster off to our left.  Below Han's blaster are the heads of Kenobi and Grand Moff Tarkin.  Below Leia is Chewbacca.  Behind the central figures are primarily blue and red images of X-Wings, Tie Fighters, the Death Star, and other familiar ships fighting.  Above and behind Luke and Leia is a dim image of Darth Vader, holding up a red lightsaber, his gripping hand between Luke and Han, and the blade extending up and do our left, off the top of the image.  Across the top of the image is a solid red band interrupted. with the Star Wars logo in solid white. In the right hand portion of the red band is yellow text saying 'The Roleplaying Game'.  At the bottom left is a flat yellow version of the West End Games logo.
