The only reason people are bashing this game (even though it HAS been downgraded fron the E3 build): this game is not GTA V.
Really, that's all the vast majority of detractors say about it.
But Watch_Dogs is better in my opinion. Tons of things to do, Chicago feels and looks real, nice story line, nice characters, awesome gameplay... A real must-have. The first real next gen game.
Now don't get me wrong, Watch_Dogs is far from being perfect. It has a lot of flaws, especially the driving and the damage on the cars, but it's a really good game, and a great start to the franchise.
Remember the first Assassin's Creed. It was flawed as well, but AC II and III were simply awesome.
People keep saying it's not worth the money simply because they can't get the idea that Watch_Dogs is NOT GTA V.
And in my humble opinion, it is better than the latter.
Think about it: Watch_Dogs gives us something new. Never an Open World city has felt THIS alive, the hacking gameplay is a great idea, and even though it could have been better, it's still a real pleasure to play it. On the other side, GTA V offers NOTHING new. So yeah, 3 characters, big deal, but that's all. It's still the same game as every GTA before.
So imo, Watch_Dogs > GTA V (but it's still a great game as well)
Just because you have an opinion doesn't mean you are necessarily right.
