Wasn't Interplay being dicks when this whole mess started and basically only held onto a "dead" franchise to make money? Bethesda were huge fans of Fallout and wanted to revive their beloved series because Interplay had no means to. After what seemed to be a Duke Nukem situation, this agreement popped up.
I was excited that Bethesda was able to hatch out a deal. Now though, they are rescinding on the deal due to the huge success the new Fallouts have garnered. On one hand, I understand not wanting others to tarnish the franchise in what many will perceive to be your game (a vast majority will never know this info). On the other hand, which is stronger and bigger (like the foam #1 hands), without this agreement, Bethesda never would have had this huge of a success. Let Interplay do their MMO. Bethesda, you should be happy with your riches. Now, you're coming off as greedy.
