With over 130,000 concurrent players and 5 million total, Ubisoft’s squad-based tactical shooter Rainbow Six Siege is kind of a big deal. Rarely in its lifetime has it ever dipped below its spot in the top five most-played games on Steam, and its clout as both a competitive powerhouse and a spectator darling have only grown with time. It’s a game beloved by its fans, and admired by its competitors. But most people familiar with the game know that it wasn’t always this way, and it took developer Ubisoft Montreal a lot of faith and perseverance to make it the success it is today. It did something virtually unheard of among AAA games these days — it put the players first.
