video game

Well, there's all that stuff with ownership rights and all. The Beeb owns Doctor Who, but the Daleks and the Cybermen belong to the men who created them. I'm going to guess that other monsters are also under other copyrights. A video game would be cool, but I doubt that anyone would want to play with the current Doctor and that's what the Beeb would probably insist on. I also doubt that anyone would want to play WITHOUT the Daleks or the Cybermen and you'd have to get the rights to them too.
