I just bought it and I guess it's kind of a mmo. I haven't gotten into it that much yet but it does look fun. Saw someone running "end-game" and it looked really hard so i'm kind of interested if other people are playing as well.
Also, PC for me with those games. I can just aim a billion times better on PC then I can on Xbox/PS4. Just more accurate really. Nothing against Xbox/PS4.
