Fans of legendary gaming properties like Warcraft, Starcraft, and Diablo can rejoice: according to Forbes, a brand new franchise is on the way from Blizzard Entertainment, the company behind those games. The new franchise, called Overwatch, was announced on Friday at the company’s annual convention – called BlizzCon – in Anaheim, California.

The Overwatch news is groundbreaking for a variety of reasons. First of all, as many gaming publications have noted, Overwatch will be Blizzard’s first new IP (“intellectual property,” essentially a gaming term for original title) in 17 years. Blizzard launched all three of its core franchises in the 1990s, starting with Warcraft (1993), continuing with Diablo (1996), and concluding with Starcraft (1998).

Since then, the company’s development titles have been sequels and offshoots of those three franchises, including 2004’s successful online RPG, World of Warcraft, and the 12-years-in-the-making 2012 sequel, Diablo III. Overwatch will break the cycle by adding a new franchise to Blizzard’s wheelhouse.

Also surprising is the fact that Blizzard already had a gameplay video to show off at BlizzCon. This fact suggests that the game is much farther along in development than one might have assumed, considering how well under-wraps it has been kept until now. The Forbes theory is that Overwatch has been “Frankensteined to life” from pieces of Project Titan, a franchise that was supposed to be Blizzard’s first new IP since the 90s, but which was cancelled this fall.

Project Titan has already become infamous in gaming circles. The game’s story dates all the way back to 2007, and Blizzard supposedly poured tons of money and time into the project before pulling the plug entirely in September. Now, though, it appears that Blizzard may have salvaged some of the work from Titan for Overwatch.

Of course, the games are not identical. Titan, like World of Warcraft, was supposed to be a massively-multiplayer online RPG (MMORPG), while Overwatch will be a team-based multiplayer shooter. But as the Forbes article notes, though, there are similarities, from the team-based gameplay to a near-future setting, all the way to the overall look of the game.

It would make sense for Blizzard to salvage some of the work they did on Titan for a new game. The question, though, is whether the long and difficult development road for Titan could leave Overwatch feeling like a gutted version of something that could have been. Only time will tell, and from the looks of it, it will tell sooner rather than later: Blizzard seems to be shooting for a 2015 release for Overwatch.
