I am looking forward to this. BBC hasn't let me down yet with their online games (see the Last Dalek game, and the whoisdoctorwho? website stuff (the latter being very fun and very imersive)) and I'm banking on this being as good especially since this will be a game with a proper story and voice acting etc.
I hope that, not for my sake but for others, that they won't call upon plot points in the games as part of future TV stories simply because that would be a little unfair. Then again I'm sure they'll have factored that in as they know that not everyone who watches Doctor Who is a die hard fan.
Oh, and free games are always a good thing, I like to think of it as getting our TV licence worth!
Oh and P.S. do track down the whoisdoctorwho? 'defending the Earth' stuff as the webpages are still out there. Oh, and P.P.S. and if you can get the Last Dalek game working on the BBC website you're a better man than me!
