Absolutely, but as far as I know 2K does not own Gearbox, they simply publish for them. If someone knows different please correct me.
And as for publishing, I actually have a couple book deals and my publisher works with me on determining what I feel is in my best interest. My publisher has never once done an exclusive (I had an offer from Amazon which I accepted) without getting my input and if I had told them no they would have taken a different route.
If Gearbox is owned by 2K this would be different.
I understand Gearbox and 2K are on a level I will never achieve, but if Gearbox had made it clear they would be unhappy about the exclusive I will bet money they wouldn’t have done it. I do know enough about business to know that a publishing deal is not forever unless both sides choose it to be, it is usually for a certain amount of games before it expires, unless of course both sides choose to continue.
