For those of you who haven't heard, Titan is a project that Blizzard has been developing in secrecy for quite some time now. The first hint that was given to the company's newest monolith of a game was back in 2007. Job listings for designers for a new project were listed on the Blizzard company website, leading gamers and community paparazzi to go on a hunt trying to figure out what those crazy guys at the Blizzard H.Q. were up to.
This seems to be a very serious project, as the Senior Designer team for World of Warcraft has been pulled and applied to Titan, and trust me, we can tell with how -well done- Cataclysm was. *End sarcasm*.
Jeffrey Kaplan (Also known a Tigole for you fellow extremists), when asked if the new Blizzard MMO was going to be science fiction, post-apocalyptic or historical, just laughed and said "all of those combined!" To add to the broad scope of the game's target audience, Blizzard said that Titan was to appeal to a "casual audience", leaving me to wonder if they intended WoW to appeal to the hardcore players? I'm sure all the EVE players out there are facepalming at speeds greater than light right now.
In any case, Blizzard has a history of making very solid games. Maybe not solid expansions, but the games themselves have always been of superior quality. I'd be lying if I said I wasn't excited for Titan as well.
