I don't think you can play some of those games you mentioned on a PC even via Emulators. Like the Last of us and The Uncharted series. Bloodborne is not even out yet.
You can more or less play those other triple A games that is available in Steam with Big Picture mode. Just buy an xbox 360 controller. If i'm not mistaken that controller is plug and play.
EDIT: Just googled ps3emulator and clicked the 1st hit. Anti-virus blocked something from that website. So yea steer clear from it.
