I cannot believe Im saying this, but: Im thrilled that Assassins Creed is huge again.Thats not a remark on the launch-window buzz for Assassins Creed Shadows (3 million players in a week) or the cultural cachet earned by its social media managers (so far, at least one vindictive billionaire defenestrated on his own social media platform). Its meant quite literally: Assassins Creed Shadows is a massive game, and that rules.Over the years, Assassins Creed games have evolved from modest open-world stealth adventures into the type of bloat thats synonymous with Ubisoft map game. This evolution culminated with 2020s Assassins Creed Valhalla, which was infamously too much game. The data-tracking site Howlongtobeat puts an average Valhalla playthrough at around 100 hours, and closer to 150 hours for a completionist run. Thats in addition to three expansions and a free roguelike mode that was practically designed in a lab to devour my time. I sunk 91 hours into Valhalla before hitting the credits, and I skipped an entire region of the base game.In the wake of Valhalla, 2023s Assassins Creed Mirage was a breath of fresh air. The entire game was situated in one city (Baghdad during the 9th century) and its surrounding area, mimicking the form of older series entries like Assassins Creed Brotherhood. There were a couple types of collectibles and a few recurrent puzzles, but gone were the byzantine menus and stat micromanagement of Origins, Odyssey, and Valhalla. Reviews (including ours at Polygon) praised its restraint, and I have to admit, it was nice to play a focused Assassins Creed game for the first time in years.But the recent release of Assassins Creed Shadows has unleashed my inner Goldilocks. Valhalla was a tour de force, but with every new gray hair I find, my patience for games of that size wanes. Mirage was a welcome change of pace, but it lacked staying power. Shadows nails the balance.Where Valhalla presented too many things to do, Mirage lacked the flow thats been present in every Assassins Creed game released into a post-Witcher 3 world. You know the one: You scale a castle spire or a giant tree or the central mast of a galleon. You scan the horizon and assess all the little question mark icons peppering your view. Then you pick one. Because maybe its something cool, like a fascinating platforming sequence over a subterranean river. Or maybe its something rewarding, like a sword with the word unique or legendary in its item description. Maybe its a quick-time event.Shadows presents a mastery of this flow state. Theres an almost meditative quality to hopping from objective to objective through the countryside of 16th-century Japan. (It sure doesnt hurt that Shadows is quite easy on the eyes, rendered with painterly beauty.) Not knowing what youll find is part of the fun. And for the most part, what you come across is indeed worth your time.Sometimes you stumble upon a castle where youre tasked with assassinating a few high-level enemies in exchange for rare armor, or you could come across a bandit camp replete with resources necessary for your hideout. But these activities are blissfully not all about assassin-ing, despite the games name. Platforming gauntlets called Hidden Trails and puzzle dungeons called kofun add some variety. Temples require you to track down a handful of hidden objects known as Lost Pages. Even the quick-time events rhythm-based minigames called Kuji-Kiri are compelling: They unlock missions that fill in the backstory for Naoe, one of the dual protagonists.To be clear, Im saying this all from the perspective of a pretty leisurely player. Ive played for a bit more than 20 hours and only just unlocked Yasuke, the second playable character. Peers whove finished Shadows say it takes about 40 hours to complete the main story, or something closer to twice that for a completionist run (a lot of time, no doubt, but significantly less than the Oh god, its never gonna end vibe of Valhalla). Who knows, maybe Ill burn out! But at this rate, the pace and the scope of the to-do list are perfect.Well, unless Ubisoft demolishes the peace with a free roguelike mode.
