I need to watch again the Killzone 2 reveal, but what impressed me on Watch Dogs was the lighting, reflections, the interactions with the scenario and... gunplay, I think? Funny that the dirigibility of the cars looks like the same.
About Anthem, I swore that I would never play any game from EA again since the Unprecedented Partnership fiasco, but the game itself was a joy to look. Maybe not on pair on what made me buy a game with some reminiscence of it, that was Xenoblade X, but that didn't felt a current generation game anyway. Worse: the vertical scope doesn't felt credible at all, especially looking at the draw-distance of it. Also from what I saw, there wasn't any underwater gameplay...
Maybe I'm too skeptical, but this will be another under-delivered game coming from a big company.
