Borrowed the PS3 version from a friend last week. Despite it being 20 hours long I managed to power through it in 2 sittings. This does not happen. I was going to pick up my own copy because it's honestly one of the best games I've ever played. Glad I hesitated though because now I'll finally have something to show off my shiny new PS4 with.
Funny story though, I was playing it last weekend and my wife came in and asked me what I was watching. I showed her it was a game and that I was actually controlling it and her draw actually dropped. :D
