I agreed with none of the criticisms of Aiden Pearce, I didn't think they were fair at all to be honest. After playing through Watch Dogs a few times and not to mention completing all of the side missions in the game, Aiden is a bad-ass nothing more and nothing less, a "grey hat vigilante". I thought the audio tapes explained him well enough and I actually identified with him, I don't know who people were expecting him to be. As for the game itself, I thought it was very good, it had the most strategic freedom I've seen in any game in a very long time for one, the side missions served purpose into showing why he was called the vigilante and though the shooting mechanics were great, the game did not reward you for reckless gunplay. It is true urban stealth sandbox that explored some interesting criminal masterminds(mainly Aiden, Iraq, T-Bone and the DedSec group, I also liked the fact that Clara's vocational was tattoo artistry outside of her being a hacker at heart, which is believable) w/ an implausibly narcissistic villain(Damien Brenks). Like Assassin's Creed and L.A. Noire, it was a pretty intellectual experience that made me use my wits and it is the only game so far, until Metal Gear Solid 5: The Phantom Pain arrives, to make tactical use of the day and night cycle. It definitely takes after the worthy Splinter Cell series like alot of you already said. They could've used more weather changes such as snow especially for a city like Chicago and some of the character designs were stupid(Defalt's mask was corny and though I liked Iraq,I can do without that dreadlock piece on top of his bald head.
I also liked how they explored how blackmail is worth alot of money in the criminal underworld and how hackers are the new masters of deception, Watch Dogs dark clouds ebook explores Aiden deeper as well. Aiden was cool with me, he was perfectly imperfect.
