PS4 is my main and only platform, really. I have a potato PC for internet stuff.
I can't really think of anything outside of my reach that I would want. Well, PC gets some RTS games and such that never release on consoles, but that's pretty much it. Perhaps the new Microsoft studios will eventually put out something that I would want, but I suspect everything from them will be on PC as well. So if I wanted to get my hands on absolutely everything of interest, I would have to invest hard into a new PC, which I'm not likely to do.
I'm very happy as I am, I've got plenty to play.
