If it's the company that you worked for, start with contacts like the last known owners of the company. Depending on the country the company was located in, there may also be public records of transfer of ownership of company assets, from courts in the district that the business was located in or local/county/state/national Department/Ministry of Business.
Thank you,
I've just tried to search for some information about that on various government web sites but it's really hard to find anything.
I guess I'll just keep trying. Maybe those organisations have some support that can help.
PeterPettersson: Is this something that GOG themselves can help with?
Ancient-Red-Dragon: I doubt they would want to do that; just because you could probably get the game working on modern computers, that does not automatically mean GOG would be interested in selling your game on their store.
GOG "curates" the games they sell, and rejects the ones that they don't want to sell from being sold on GOG.
It wouldn't make sense, financially speaking, for them to spend their time & money trying to help someone find the IP owners of a game that they don't even know that they'd want to sell. And they also wouldn't know if you could resolve the legal limbo even if you did track down the owners, which would give GOG even less incentive to get involved with helping you in that regard.
Yes, I see.
I was hoping that since they've have some experience with this they might have some documentation or tips on how to approach it.
Can you find the credits for the people who actually worked on the game? Like a director or similar. (maybe on Mobygames) If you can find some of the main people (find their names, then see if you can politely contact them via LinkedIn, Facebook, Twitter, email, etc.), they may be able to help.
I know most of the development team, but none of them have any ideas unfortunately.
The owner of the company seems to have completely disappeared, I can't find any info about him.
PeterPettersson: ...I saw that an old game I made...the company who made it...
AstralWanderer: Some clarification would be welcome here. Did
you write the game yourself (and then license it to a company) or were you part of the team that wrote it?
If you were the sole author, and used a "standard" contract to license it, then it may be that the copyright granted to the company reverted to you on their closure, in which case you can contact GOG as the rights-holder.
I was the lead programmer. It was a team of about 10 people all in all who worked on the game. Half were regular employees and the rest were contractors.
I believe the company we worked for owns the license as no publisher was involved until the very end, and then it was different publishers for different regions around the world.
