Today marked the launch of Watch Dogs, a highly-anticipated action-adventure game from Ubisoft. Early reviews for the game are fairly good, but not without complaints. Eurogamer said, 'Combat encounters also draw inspiration from existing games, with slightly stiff but workable sneaking and cover mechanics and decent if unremarkable gunplay. ... There's a sense of sterility beneath the surface, though. As dazzling as the game can look, this Chicago feels like a place you travel through rather than a world you inhabit. Pedestrians gasp and gawp at car crashes, but exhibit no real life.' Polygon's review complimented the bits of structure within the open-world game: "More than any stealth game I can think of, Watch Dogs does a remarkable job in allowing for proper preparation. It creates a universal environment of constant puzzle solving, which sits cozily next to all the action on display." Rock, Paper, Shotgun added, "It feels churlish to complain about something which is only magical 90% of the time, but in some things, ten percent can seep out and render the rest infuriating and useless." It's worth noting that some users are running into problems even playing game, thanks to authentication issues with Ubisoft's UPlay digital distribution service.
