Ray posted this about Return to Krondor:
Dynamix, 7th Level, and Pyrotechnix employees created all the characters that weren't in the books prior to the games, i.e. Limm, Lysle, Jazhara, Sidi, etc.
It could be any or all of the above. I think most people found BaK did a better job of doing what it set out to do than RtK did achieving its goals. There are many reasons, but in short, it works or it doesn't. For me, they both had problems (in fact, Bak had many more story problems than Rtk, while RtK had more game problems than BaK).
It has NOTHING to do with my novels. It's 100% unrelated. The marketing department at Sierra decided to name it 'Betrayal In Antara,' to attempt to capitalize on BaK. We hit them with a cease and desist letter when they tried the first press release calling it the 'Sequel. . .' They stopped that rather than face a lawsuit they couldn't win, but they did get heavy into the 'from the people who brought you BaK,' which was techinically true (same parent company) but factually BS (everyone associated with BaK was long gone).
Nothing at present. We're at the last stages of disentangling ourselves from Sierra now that Pyrotechnix is dead.
