I've been reading some articles online and a lot of people seem to think that Titan is going to be a science fiction based MMO, but not in the Starcraft universe. Some people are saying it will take place in the Halo universe (no idea how they came up with that one). From all the information I've gathered, it seems like it's definitely going to be Science fiction, and possibly from the first person point of view. My first guess is that it's going to be a "mech" style game that you can play in either first person, or third person view, and you customize your "mech".
My second guess is that it will be a DoTA style game, only set in a science fiction universe (their job listing says "next gen mmo", not "mmo-rpg, so it might not even be an rpg).
Of course I could be totally wrong, but what do you guys think it will be?
