Well, this discussion seems old. From when graphics progressed at their fastest pace. And it seems I've seen it more about FPS games. There was a time when "the best" FPS was always the one with the highest definition of visuals. Or so was the gist of the cackle.
There are so many things in the air here. The degree of definition. The degree of realism. The degree of visual attractiveness. The efficiency of conveying an atmosphere. The mood. The agreeability and suitability of art style.
But is it even a relevant discussion? The games are quite different, and thus all those things in the air serve slightly different goals.
I will probably buy both games. But for different reasons. I'm very keen on DA:I, but will buy TW3 mostly for support and to have a firsthand look. I doubt I'll play it much.
I like a lot of what CDPR do. I like that they take themselves seriously, and their game seriously, and make a game as they, the creators, visualize it, rather than as what a clueless marketing department thinks 14 year old boys would get excited about. The atmosphere and mood in TW2 was fantastic, and greatly refreshing after DA2's remake of DA. In that regard, I think CDPR represent a direction that I would like to see many more games take. And I think it's a direction more video games should venture out into, rather than staying in that same clich'eed, video-game'ish duck pond all the time.
(I'd like to point out CoD as well. The first games had a very realistic, authentic atmosphere, as in actually being there and then -atmosphere, rather than watching any utterly unreasonable and idiotic Tom-Cruise-Mission-Impossible/Matrix3 nonsense-action.
Then gradually, CoD was turned to different developers, and progressively started to deploy things like 600 meter scooter jumps and what have you. Finally, they arrive at 'Avanced Warfare', which is just yet another of those gimmicky console, non-stop-shooting-galleys which were always made in scores, but didn't sell so well. To me, the end of the CoD franchise was some time before this. Am I so wrong in thinking that CoD's attraction, originally, was its sense of authenticity?)
But, returning, TW2 and TW3 doesn't interest me that much as games. They are twitch-games and have a very fixed protagonist. Nothing I look to RPGs for. So my main interest is in DA:I. I wouldn't like to say anything about the graphics before I've played the game. Only then will I know how I've taken to them. But my main focus will be how effective it is in supporting an atmosphere, rather than the technology's actual degree of hi-definition.
