My favorite thing about Assassin's Creed IV, released for PC earlier this week, might just be the unisex bathroom.
That's not a slight against the game at all. Though I've yet to finish it, so far it seems to have taken all the best lessons from the run away success of Assassin's Creed 2 as well as the mixed reception of 3, leading the series' latest iteration to blend the fun characterization of the former with some of the impressive mechanics introduced in the latter. Top everything with a healthy dose of game industry self-awareness (right down to notes in the lore files) and you have a recipe for one hell of a game.
Then, you step back from all the freerunning, shark-hunting, and swashbuckling... And by "you", I mean the character you're actually playing.
