RPG's, as I prefer a solo, cerebral experience. Never was good at FPS, except for Goldeneye 007 back in the day on N64.
I'm about 10 hours into the game, but I like to take my time so haven't gotten far. Basically, if you enjoyed Skyrim and Fallout 3, then you'll enjoy this. Fallout 4 is built on essentially the Skyrim engine, just with an impressive upgrade to animation and textures. Still concerned about the main story, but we'll see.
It's the best from last year, far better than the shit storm that was Unity. Takes what Black Flag did with gameplay, and takes a story turn that was interesting to explore.
