I don't read Sci-Fi that often, I'm more of a fantasy reader. But I liked Carve the Mark by Veronica Roth, more or less a mix between the two.
My favourite Sci-Fi videogame (excluding cosmoteer) is Titanfall 2. Who doesn't like giant mechs with an own personality? "Negative, I will not lose another pilot!" (That sentence gets me every time.)
About movies, well. I like most Sci-Fi movies that aren't horror (like Alien, although I can appreciate the atmosphere that those movies create.)
