Watch Dogs 2 is a low-key masterpiece imo.
The story itself is kinda dumb, however the actual main missions were fun as fuck to play through. Loved using all the tools and hacking abilities to stealth my way through.
The city is beautifully designed, and only rivaled by GTA 4 and 5's Liberty City and Los Santos imo. WD2 even beats them in some areas such as npc behaviors.
I personally liked the "hipster" characters, as I thought they fit well with the setting. Plus the acting was top notch. A lot of people thought they were goofy, but I saw them as mostly inexperienced, somewhat naive, and idealistic. Like....a bunch of young people! I can see these characters maturing with age, looking back at their early years in DeadSec with both "good ol' days" fondness, and "oh God we were so young and cringey back then haha" embarrassment. Only character I was annoyed by was Wrench.
It's also the only open world game other than MGS V where I played mostly non-lethal, not because you get penalized for killing (like in MGS5), but rather it didn't feel right for the protagonist to kill. Good thing the game provides you with all the tools (taser, electric bombs, hacking, non-lethal assault rifle, etc) to accomplish this. Looking back it would've been better if they penalied you in some way for killing (for example you lose "likes" for killing too much), since I've seen a lot of people complain about how it doesn't make sense for Marcus to kill so many people (like yeah, that's why you can clear every mission non-lethally, but whatever).
9/10 game for me.
