In 2007, Blizzard hosted forums on a new MMORPG, as Blizzard's site saw job advertisements. Blizzard confirmed that the bidding was genuine and that the game would not be an expansion for World of Warcraft but a completely new universe.  In November 2010, a timely schedule was published, which, among other games of Blizzard, also represents the game Titan with a release in 2013. In 2010, Blizzard's CEO Michael Morhaime said that Blizzard has learned from World of Warcraft and that this knowledge is needed for Titan. In addition, he believed that Titan and World of Warcraft could be together in the MMORPG market, as Titan will open a whole new genre for the gaming industry.  In March 2011 Blizzard confirmed that the game is already playable internally and is planned for the next ten years. In September 2012, about 100 developers were working on Titan. 
On May 28, 2013, it was announced that the Titan team would be restructured. 70% of the designers will switch to World of Warcraft, Diablo III and StarCraft II. In addition, the secret planned publication period was moved backwards. In August 2013, Morhaime confirmed that the game was going to be a new direction and it was normal for Blizzard to have a long game.  On September 23, 2014, it was announced that Project Titan was no longer under development. 
"We did not find the fun. We did not find the passion. We're talking about how we're doing it. The answer is no. "
"We did not find the fun. We have not found the passion. We talked about how we can recreate the game, and we asked ourselves if it was the game we really wanted to make. The answer is no. "

Shortly after this announcement several game details were announced. Thus, Titan should be an MMORPG and the action should take place on a future earth. On the day you should do jobs, while you had to defeat enemies in the night. The game details were released by former Blizzard developers, but were never officially confirmed. 
Overwatch was officially presented on the occasion of the BlizzCon on 7 November 2014. Blizzard confirmed that many of Overwatch's themes were from Titan, and Titan's game had evolved. Thus some cards and heroes from Titan were taken.  First, the idea was to offer the game as a free-to-play game supported by micro-payments. This business model is also used at Blizzards Hearthstone and Heroes of the Storm. At BlizzCon 2015, however, Blizzard confirmed that the game would not be free-to-play because it would not work in game.
