3D PRINTING IS THE SHIZNIT!
One of the more fun things this game can do, would be action figures of YOUR characters. Not just statuettes or mock ups but actual action figures. Using the Character creator model/frame, add in spots for the joints and stuff, so they would/could grow with the model, and team up with any of the numerous custom figure companies out there. There is an entire slew of smaller companies that would love to have an official license to this stuff. Weapons and items would be made based off of molds and such, while the bodies and parts themselves were made from the model of the characters. They could add money sinks by allowing for part picking from accessories and weapons, or generic parts (hands/feet in various poses), and for extra money, they could even be painted by a person to be the colors they are in game.
Granted, this wouldn't be cheap, being anywhere from $25 for a 3.75 inch figure to $80 for a Fully painted 6 inch figure. Guaranteed to be on the expensive side but people would totally pay for this. More so, if you could pick parts, buying just the custom heads or torsos or capes and such that they could add to existing figures and paint themselves.
