I think using the video game system of offering DLC to already COMPLETE and FULLY CODED pinball games an exciting idea.
Think about it, Aerosmith is looking like an amazing game, but after time when the game is fully coded and complete you will be wanting more songs.
So what if every few months or so Stern released themed DLC packs. Such as "Mama Kin DLC" which adds the song, along with new lighting, rules and sounds that incorporate the song's theme. Or even "PINK DLC" which adds the song and gives the playfield pink lighting. Or even a "RUN DMC DLC" which adds them to the game, where you have to recruit them for Walk this Way, or make shots to ensure they play in time together.
Hell, if they release a new album how about a chance to add that to the game too?
Fantastic!
They could even do yearly updates for sports games like 2K does. With Stern's Wrestlemania they could make yearly updates to the code to add the current roster, entrance music, and custom call outs from the current wrestlers. Or even add more legends!
They could change $30 or so for the DLC which should inspire Stern to keep working on new ideas and improving their games. People shouldn't have to work for free!
To clarify all the confusion about this idea, I repeat I am NOT talking about paying for code that should already be in the game. These are extras thought well into the games existence to freshen things up, and keep an old title feel like new.
Happy pinballing everybody.
