Notes:
This is perhaps the highest-quality Present Day mission overall in Assassin's Creed 3, possibly the entire Assassin's Creed franchise. Why? Because it represents all of Assassin's Creed 1.0's Core Pillars, in Present Day form. The Brazillian MMA Stadium gives players Social Stealth, Line of Sight Stealth, Complex Parkour, and Combat, all in one mission. It is a blazing beacon of glory for the Present Day setting and one of the highest points in the entire series. It proves that this kind of gameplay works in the Present Day setting, and it works well to create engaging, high-quality missions for the player that have just as much impact as a Historical Memory with the same rulesets and mechanics. While I do not believe a Present Day Open World is possible inside of the same game as a Historical Open World, I firmly believe that Present Day Missions played in a linear, sequential order with this level of complexity and mechanical richness are very possible, and should still be demanded.
