Best way to advertise your game?

Put it on a few forums but I should warn you. You can not sell it or a man in a suit will sue you for lots and lots of money :)

Create a profile page on social sites such as Facebook, Twitter and Google+ and attract attention towards your game by sharing information about it, engaging with your friends and asking their feedback.

Make sure that you are providing your game for free as it is based on Dr. Who. Like @The Shadow said that it is illegal to create video games on something official without taking permission from it.

wouldnt name it doctor who sole reason that screams lawsuit pretty sure they would have copyright over the name even if you arent selling it if the name is patented then you will be be taken to the cleaners lol.

also im pretty sure that a game company owns the right to doctor who based games.

You should try video marketing. I recommend you using this software - http://www.youtube.com/watch?v=WXzZMRxhn98&feature... it has the software link in the description and it tells why the software is good and all and some of it's features, this software should help you boost your profits to your business but I recommend you make a website for your business first then use the video to draw traffic to your website then use the website to draw business to you, then you can post the videos on social media sites and youtube and other

I understand that age is a important factor if it comes to performance. I think you should search google for some sites for your game to advertise.
