This game is BROKEN on PC. You have to jump through hoops to get it in a playable state. Beyond that, the gameplay, is incredibly barebones and unengaging. The parkour, the atmosphere and the intrigue are the best aspects of this game, however, the parkour is noticeably clunky at times, the atmosphere is very hit or miss, and the intrigue doesn't get all that good until the end once you have read the Abstergo logs. Don't play this game unless you're a die hard fan; start with literally any other game.

The gameplay loop is still as solid and as fun as it was in Mk DS; the removal of a dedicated missions mode hurts, however, the addition of Kart customization, gliding, underwater segments, ramp boosting from the console games, first person and so many other things, brings this entry up to the same level as its predecessor, in my eyes.
