Setting aside the visual beauty of AC Odyssey, or the visceral thrill of assassinating targets, what Ubisoft nailed with this game is the addictive RPG loop. Complete a quest, get rewarded with new abilities and gear, try out those new bonuses on the next quest. That cycle kept me hooked for more than 100 hours of play - and for better or worse, there's still much more of the game I haven't gotten to.
