The player guide and corebook, both digital and physical, are included in a lot of the tiers, excepting the lowest ones. We are limited in the amounts we can offer both digitally and physically (Monte doesn't want to give away thousands upon thousands of copies of his hard work, obviously, he still needs to sell em) so we can't do it as an add-on, but they're in there for many tiers.
I presume that the rights holder/s get the money.
IP & distribution rights don't simply disappear. They are bought, sold, sub-licensed, etc. There's always somebody willing to buy old IP for a small amount of money.
If a games company goes bankrupt its IPs are sold or auctioned off. See the THQ situation at the moment.
Sometimes there are time limits or certain conditions upon which "the rights" (whatever that specifically means) fall back to the licensor.
PB owns the Gothic brand and all rights for the first Gothic. Whoever sells Gothic 1 made a deal with PB.
Observation tells me that the publishing and distribution rights for G2 and G3 still reside with Nordic Games, who bought them when JoWooD went belly-up. Deep Silver seems no longer involved, although they were co-publisher for G3.
Thanks. Have to say I'm disappointed but that's pretty much what I expected. While GOG is great for keeping games alive for gamers a successful Good Old Game makes precious little (monetary) difference to its creators if a company has already gone down. Successful gog.com stories for games by the likes of BlackIsle or Troika are ultimately meaningless (if you don't care about GOG or CDP itselft, that is).As others have said, rights holders. Interplay for Fallout currently, with Bethesda taking over in 2014. Hasbro is the rights holder and publisher of Planescape: Torment.
