Tom Clancy's Rainbow Six Siege

Announced at Electronic Entertainment Expo 2014, it received four nominations from Game Critics Awards including Best of Show. The game received a generally positive reception from critics, with praise mostly directed to the game's tense multiplayer and focus on tactics. However, the game was criticized for its progression system and its lack of content. Initial sales were weak, but the game's player base increased significantly as Ubisoft adopted a ``games as a service'' model for the game and subsequently released several packages of free downloadable content. The company also partnered with ESL to make Siege an eSports game. Two years after the game's initial launch, the game had 25 million registered players.
