Quoted from Bronty:
I know this is probably an old topic so excuse the question, but licensing issues aside, what 90s bally/williams machines do they have the info to remake? All of them? Is it just a question of which ones are worth the time and trouble to remake, or are there other factors? I guess what I am asking is, do they have the rights to the entire line up?
Rick has said that PPS has the right to remake all of them as far as B/W is concerned. Additional "licensing issues" arise where the game itself uses licensed IP, and there's additional opportunity for difficulty and cost if actors are depicted in the art. Pinball Arcade has paved the way with some titles, showing that licensing issues aren't insurmountable (e.g. MB). Some others you could imagine being much more difficult (e.g. TAF, where Pinball Arcade ultimately had to redraw the art b/c they couldn't negotiate likeness rights with Christopher Lloyd and Pugsley). It's also conceivable that some IP holders have exclusive agreements with Stern that could make remakes tricky (e.g. IJ, Star Trek). Most people and all corporations like making money, so most of the classics should be "remakeable" if PPS/CGC are willing to put in the legwork to negotiate licensing.
As for licensing costs, this interview with Roger Sharpe is interesting, he says all the licensing deals he's ever done were for "far less" than $100 per machine.
If that holds true, licensing costs really shouldn't be a huge factor in deciding which games to remake next. Of course the hassle of working out licensing might be a consideration, and if you run across a Christopher Lloyd that just doesn't want his image used, you're going to have to redesign the art (imagine the blowback on Pinside!) or pick another pin to remake.
