Hmm, watching those videos really makes me want to grab a PS4, but I just find that once I'd played it through, I wouldn't have anything else to play. Nothing else really entices me, as I'm not really as much of a gamer as I was some years ago.
I'm hoping that me waiting it out until the end of the year will allow me to pick up a better version of the PS4 - such as one with a bigger hard drive - and potentially the game for cheaper.
Looks fun though!
