Titanfall was made by two different devs and it's still the same game...

I disagree with the Second and Third party definition. Heavy Rain isn't owned by Sony, yet Quantic Dream is a Second Party Developer.

Sony owns the Demon's Souls IP, but From Software is a third party developer.

I think Second Party just means a developer who publishes a game exclusively on one console, no matter who owns the IP.

Well I for one appreciate the cross gen. The X1 not even being a year old I appreciate the option. The hypocrisy here is kinda funny. Now that MS is supporting their console (in its NINTH year), people still complain.

I don't understand people complaining about a cross-gen title. It's a unique idea for consoles and if it works, people who own an X1 can immediately bank on a much larger player base, people that own a 360 might be influenced into buying an X1 after playing with their next-gen counterparts, the developer gets the assurance of their title getting released to the largest possible audience...
I mean I really don't see a downside.

sorry but heavy rain was originally slated for both ps3 and 360,..  it is a third party exclusive.  it is no more sony's than the witness, exlusive because they found mutually beneficial terms (marketing) but sony has no real ownership in the games. 

demon's souls is a second party franchise hence why from software had to abandon the IP and create dark souls to go multiplat.  ratchet and clank/insomniac is also second party hence why insomniac is free to pursue multiplates and xbox exlusives on the side,.. just not with the R&C IP. 

Incredible how minor differences between PS4 and X1 games are enough to buy one over the other but when it's 360 vs X1 the difference isn't large enough to buy one over the other... this is actualy funny

Awesome, so it's official now. I loved the first! Absolutely awesome game, underrated in my opinion. The game looks absolutely stunning, still today.
I expect both versions to differ a lot. Graphics and content. The number 2 won't improve much on 360, for sure, but I am eager to see what they can do on next-gen! Should be a legit competitor to DC.

Are you saying that Forza Horizon 2 is a 360 port?

If History of me arguing about Heavy Rain with people around VGC has taught me anything, is that a 360 version was remotely considered...back when the game was on paper only. When they start making the prototype for the engine and the game, it was already funded by Sony . So you could say Quantic Dream chose to be a Second Party developer; (seriously, Nintendo or PC wasn't even considered. That makes them even more Second Party). I think Beyond: Two Souls is also owned by Quantic Dreams.

Anyway, I just checked the internet and apparently, "Second-Party" term is just gamer slangs; because no thing as such exists. World is divided between First and Third party.

He did in no way.
