I have to agree with you there. A truly magnificent game and one which also looks mighty impressive too. Having seen and played the 360 version also, I was quite surprised how much power could be eked out of the aging console. In a good way! And ofcourse the X1 version takes it up with the PC version; yet further.
Game itself as I've said a few times before is also well worth playing. The larger areas, extra diversity, and well just all-round tweaks and improvements to the original make it one of my favourite (and best looking!) titles of 2015 and no doubt beyond.
