Just a thought for your next game: same concept as Game Dev Tycoon, but broader.
The two main project types would be creating/producing your own work (to self-publish, or to send to a third party publisher), or publishing the work of others. i.e. build your company up into either a production company or a publishing company (or a little of both).
On a more specific level, the projects would include video games, movies, shows (for streaming/webcast or traditional broadcast), music, or literature (possibly more things?). Followed, of course, by topic/genre selection. I imagine shows would run for a set time, but would give the player the option to make another season whenever (like an expansion for an MMO in GDT).
The option to make adaptations or tie-ins would be great. Movie adaptations of video games and vice-versa are obvious, but any combination in any direction should be possible (as a real life example: The Amory Wars, a comic book adaptation of Coheed & Cambria’s music). Or the option to make two disparate versions of the same thing that are technically separate but intricately linked (like the Pokemon games, each new title comes in 2 versions and a third version comes later).
