The cutscenes look good (no surprise there!) but in-game footage on youtube looks terrible. Just terrible. Even when you do not take the reveal CG trailers into account. The only exceptions to the absolutely mediocre graphics are the manhole explosions and the water, which look absolutely fantastic!
I predict that the ps4/x1 exclusive Watch Dogs sequel will look great, all next-geny and stuff. The first game, however, looks like crap compared to Second Son or Sunset Overdrive and there is no way I can enjoy a game that looks that bad.
I think GTAV on previous consoles might look better, thanks to the superior art direction. We'll see what the PC/next-gen ports for GTAV look like.
I strongly recommend to people that they watch in-game footage and read reviews before they pony up for this game. STRONGLY!
I'm predicting a sub-80 metacritic score for this game. We'll see if I'm right.
