Ok, let's say JJP says development is done on a game, they created all of the promised code. Would you pay, and how much would you pay, for additional code?
I could forsee additional media/animations/callouts. How about additional licensing deals to add in more of the original intellectual property and collateral from a given franchise? Deeper or modified rulesets (maybe you can choose when the game starts)? Maybe a completely new game using the same playfield but offering up a completely different experience? With the light control and the LCD screen I could see possibly re-theming maybe from a different point of view, more storyline.
Updates over wifi? Backups over wifi? Remote control play? Customizing more details, like adding in additional rules (like ball saves in specific circumstances) through an editor?
In essence, is there any potential market for JJP to offer "DLC" (downloadable content, a thing in other gaming worlds) or game enhancements, of sorts. Is there a next step to take past the LCD and RGB lighting that the latest era of games all have.
