I'm new here! I noticed that Syndicate is big seller on GOG, and i wondered - are there any plans to release Theme Park, Theme Park World, Theme Hospital, or other Bullfrog games like these? It would be great for these games to be made available once again.

It would be great and shouldn't be a problem for GOG to obtain them. I don't know why they haven't released them already.

There are plenty unreleased great games that GOG has already signed. It's their business plan.
