Something else I thought about, but I'm not sure if this is really a good idea or not. Of course, with the exception to game design, there's really nothing that would hold a person back in terms of resources. Even if you can't do your own, there's a lot of free scripts available, and some really cheap, along with a boatload of resources available through the RM store for very little money. So technically, you can switch up the RTP with really cheap resources as well.
Aside from this, however, I can understand with legal contracts, copyrights, fees, collecting money, and whatever else can get in the way of people selling their game.
But we also know it's possible, and some have made a decent success out of this.
If people are intimidated by the process, most notably first time game designers breaking into the commercial environment, perhaps they can contract on with another successful designer that already knows the process for assistance. For example (using Shaz as an example, not necessarily saying Shaz should do this), Game Designer A (GDA) makes a game he wants to sell, but he doesn't know where to go from there, so maybe Shaz could charge a fee and be willing to extend his hand through the process and show GDA what he needs to do.
Next game, GDA will know the process, and maybe in turn he'll be willing to teach it to others as well.
