Yes, I have just managed to platinum the game (with a little help from the internet).
I'm really, really satisfied with this game. It hasn't delivered a mind-blowing experience in the sense of exploring something truly new, but it has something which way back in the Zzap 64 days would've just been rated as 'gameplay'. The game feels fantastic to play and it's that feel that drove me through 3 playthroughs and even now makes an Ironman playthrough quite tempting.
I'm not sure how Machinegames got it right, but the leaning system is a factor ( it's intuitive, versatile and easy to use) as are the ways weapons are implemented (dual-wielding, silenced weapons and the LKW each again offering that versatility) and I think most of all a focus on making every moment of the game itself as much straight-up fun as possible.
I think when you factor in the really quite marvellous story and cutscenes, you then get a game which is really, really special. It's the best game I've played on the PS4 and - coming back to FPSs after stopping playing them after the Doom / Duke 3D / Rise of the Triad days and then trying CoD - it takes all the good bits of CoD and dumps the stupidity and the disposability of the campaign and mixes it with the trust that the older FPSs had in the player.
So, yup, not sure if it will be my favourite game this year but it's really damn good.
