Why does Ratchet & Clank Have Different names in Europe?

With the exception of the first game and the PSP version (size matters) the games have always had different names in NA to what they have in Europe for example:

NA Ratchet & Clank: Going Commando = Ratchet & Clank 2 in Europe

NA Ratchet & Clank: Up your Arsenal = Ratchet & Clank 3 in Europe

NA Ratchet: Deadlocked = Ratchet: Gladiator in Europe

And now the latest installment has a different title also (but not as different as the previous games)

NA Ratchet & Clank: Future Tools of Destruction = Ratchet and Clank: Tools of Destruction in Europe

Does anybody know why this is the case?

Is there any other game franchise out there that cahnges its name for different continents?

My curiosity is bugging me.

Cool:lol:

I'm sure it says "Ratchet and Clank : Going Commando" on my PAL version

The newest one is Ratchet and Clank Future : Tools of Destruction here,but not Ratchet and Clank : Future Tools of Destruction.

Developers from Insomniac said they wanted to make it clear this was a new-gen console game, so "Future" is put into the title behind R&C.

Putting the colon before the word future was a typo by me. However if it is the case the word future is to symbolise next gen why did they leave out the word future in the Euro version?
