GOG now has two Relic games. It's only a matter of time.

I don't see how Company of Heroes has anything to do with Homeworld Remastered Collection. And although these are Relic games, the Remastered Collection was created by Gearbox Software, with some help from BBI (where some of the original Relic development team who worked on Homeworld in the past are employed).

To answer your question: it may be a long time before that game gets released on GOG.com, maybe never.

I am afraid that Shukaku is right. Relic sold their IP on auction. Homeworld has been purchased by Gearbox and Company of Heroes has been sold to Sega. Appearance of Homeworld on GOG does not bring us any closer to re-release of Company of Heroes.

COH is now owned by SEGA. up to them to release it here.
