In order to expand your machinimas, it is highly recommended for you to create pages for your machinima's characters, episodes, seasons, etc. This would help provide more information and proof of your machinima being in production, besides just external links. You can create your machinima characters' biography, trivia, voice actor, etc. For episodes, you can create the episode's plot, the characters that appear and even add the video to your episode's page, which can also help increase the number of views for your video.
