The movies do explain a lot of Star Wars so if you ever do feel like watching them you should definitely give it a shot. Also, not sure if you're into FPS, but if you are you could try the Star Wars Battlefront 3 beta on the PS4. I'm sure they have it on there too. I'm an Xbox One owner so I'm not 100% sure.
I believe it is on the PS4, yes. I own it on my PS Vita, but it's also on the PS3. There's also the other anime fighting game called J-Star Victory VS + that's 3D and is really fun. I own that on my Vita and PS3. The characters are all from Shonen Jump mangas though. It's a fun game though except the splitscreen is terribly tiny lol.
