I'm not an expert but did run a business or two.
In my opinion there is 5 to 6 competing factors; How difficult to get the license, how expensive is the license, what is the current market for the target machine, how popular is the target machine, how difficult to manufacture the target machine and how badly does the principle company want to turn out the target machine.
I have seen the most obscure stuff brought to market because it was someone's passion project so you can't rule that out being a factor.
Twilight Zone, Indy and Addams family seem good targets from the popularity & price (profit) point of view but I'd imagine the licensing would be hellish with overlapping parties involved. I'd IMAGINE that Twilight Zone would be the easiest with only one major figure (Rod Serling) involved plus the studio, CBS. But that would depend on how reasonable is the estate whom holds the rights to Rod Serling's likeness and voice?
According to Serling's website CBS owns everything related to TZ lock, stock and barrel.
Edit: I forgot to mention an example of how EXPENSIVE it can be or difficult to get some rights for a game. MJ Fox wanted nothing to do with BTTF when it was done by Data East and Sigourney Weaver is NOTORIOUSLY expensive, so much so that PB could not or were unwilling to secure the rights for her in the Alien game.
In Ghostbusters she is just a plastic near the library and even then its the "gatekeeper" character so maybe she did not have rights to it.
