This looks great

Looks cool, but another MOBA or MMO? I'll pass.

I watched the story trailer. Now I'm going to imagine it's a sprawling single player epic and not just another multiplayer shooter.

I like you and your imagination. It does seems tad optimistic. Got the only only pvp vide from it. 

I wonder how Gearbox feel right now

Yes, and what they made publically known was that they were working on a project which was codenamed "Titan".

Is this a new IP?  We have no idea.  It's a codename.  It's unlikely it was tied to anything existing, but can you say that with certainty having seen the game?

If the title is really, really bothering you, I can change it.  But like Talal says. Blizzard themselves were spouting this during the presentation.

Okay, so then let me explain it.  The first game was a 2D fighting game, Blazblue before it was born.  The second game was a weird action-adventure-RTS hybrid.  It bore the name "Guilty Gear 2" and carried on with the story and the characters from the first game.  Is that a completely new IP because it's shifted genres?

Similarly, where do you draw the line with changing genres?  Are Rayman and Rayman 2 separate games?  One is a 2D platformer; the other is a 3D platformer.  Is the separation the dimensions the game is played in, or does that not separate them?

If so, do you consider New Super Mario Bros and Super Mario 3D World separate IP's, or are they both the same IP because they're platformers?  Because if dimensions don't matter, they'd be the same.  If dimensions do matter, then does that mean that Yoshi's Island is the same IP as the New Super Mario Bros. games because it has characters from the Mario games and is part of the same genre?

And this is the point I'm trying to make.  You'll be making arbritrary rules until the crows come home if you decide to classify different IP's in the way that you're suggesting.  If you define games as being related based on their setting, characters & lore etc. (i.e. this game has shown nothing so far related to Diablo, Starcraft or Warcraft) then you have some way to qualify the situation.

But, since this title seems to have caused more trouble than it's worth making the thread skew off in all sorts of directions, I'll just change it.

Yes, I can guarentee it was a "new" IP. :P

According to Blizzard at Blizzcon, the cancelled "Titan" MMO actually "morphed" into Overwatch.

Listen, the title is changed, be happy.  Perhaps discussion can move back to the actual game now instead of this endless back and forth about semantics?  

You can e-mail Blizzard themselves and pretty much every news site on the internet to tell them it's not their first new franchise in 17 years, if you want to debate it further.

Twitch shooter comeback time! love it.. looks fun and great
