The people who make MMO juggernaut World of Warcraft have another massively multiplayer online game in the works, a game they're calling Titan for now. Blizzard calls it "awesome" and "ambitious". And one analyst calls it "casual".
That analyst would be Stern Agee's Arvind Bhatia, who writes that Blizzard Entertainment's next products are "expansion packs for Starcraft and World of Warcraft, a new Diablo game, [and]a new casual MMO" will "likely be released in the next 12 to 24 months". Bhatia clarified with Gamasutra that the "casual MMO" he was referring to was, indeed, Titan.
With World of Warcraft appearing to have reached its player-base cap and Activision more reliant on Call of Duty to be a success, a newer broader market for Titan would make sense - even if we don't know just how "casual" this game is expected to be.
