God dang it... Driving is... ohmahgawd... the multiplayer is stupid fun. Watch Dogs 2 looks promising, but I'd wait for reviews. I'm not really trying to deter you from buying Watch dogs if you want, it's really cheap.
The game was supposed to have amazing graphics, yet Sony (I think?) told the developers to take out a lot of their graphics work. That was the main issue when the game came out, as many players felt robbed of the experience. And yeah, the storyline isn't that great.
