Any of the big games don't take bitcoin as payment. Everything else about the game that makes it stand out are explained in the proper channels.
What are those proper channels, via Email? There are many reasons why members will be reluctant to receive an email from you, at least for now. If you believe that the game you want to build has stand-out features, then make them available in this topic, if 'investors' like the idea, then they can 'arrange' for subsequent discussions with you off the forum.
