What would be super neat would be something based off a common theme, whether it be a TV show, book, or video game.
For those unfamiliar with the game, maybe the post could include some pictures or a video showing the theme/idea of the game/tv show/book.
For example, if we were to make houses based off the video game Legend of Zelda, Skyward Sword, we would include some pictures of houses, concept art, and maybe a video of the inside of a house already existing for inspiration. (including colour schemes and others for more 'abstract' games.)
