I liked Toombs's character actually. He kinda reminds me of a Barbossa type character from POTC. He makes a good villain but in the right circumstances I could see him begrudgingly teaming up with Riddick.
i'd also love to see a 3rd and final Riddick game that ties into the beginning of Pitch Black. The ending for Dark Athena was piss poor and left a bad taste in my mouth. And Johns being sedated for the entire game just because they obviously couldnt get Cole Hauser back for the voice? Come on, surely a soundalike would of done. nobody would of complained if it was decent enough.
