[b]Mille/b]: [i]When Infogrames bought GT Interactive, they did seem to lean a little more toward family oriented games, and though that was a small concern for us it wasn�t the impetus for this deal. It was really just a case of both companies, through discussions that began near six months ago, realizing we were no longer the best fit for each other and that the best thing to do was find a new publisher. Take-Two was an obvious choice for us because of our existing relationship with them, including our other big production, Max Payne.[/i]

[i]Under the deal, The Gathering will publish Duke Nukem Forever for the PC and [b]Take 2[/b] will own the rights to the entire back catalog of PC and video game Duke Nukem titles, as well as rights to future products.[/i]
