@greyarea The end-game boss fight with the helicopter was really grinding my gears for a while. I do wish they'd followed the Deus Ex playbook of allowing stealth mains to bypass boss fights through subterfuge, rather than the Human Revolution school or locking you in a room with a murderous psycho.
But I agree, the rough patches aside it's done espionage, geopolitics, and social/conversation type encounters better than any other game I've ever seen. A hidden gem.
