Pro Rejected games get a response
GOG.com has a policy of always providing feedback in regards to both your game and its place on the platform. Though it does appear that it is often a form letter with little changed for each developer. So while it may be difficult to know exactly why a game was rejected or if GOG even actually looked at it, there will at least be a confirmation of rejection.
Pro Every accepted title receives extensive promotion
For every new release, GOG.com provides a multi-platform marketing campaign and a prominent feature on their website.
Pro Helps foster community around your game with on-site forums and user-created lists
Each game on GOG gets its own forum on the site for player discussion. It may also be added to lists by users which increases visibility.
Pro Possibility of advance on royalties to help you complete your game
GOG offers the possibility of an advance on your royalties if you're chosen for their platform. If you take the advance, your revenue split is dropped to 60/40 until the advance is repaid. Could be a good way to get your game across the finish line.
Con Only a few games are accepted each month
Because GOG.com gives every release a period of "top billing," their acceptance rate is inherently limited.
Con Copy-paste rejection letters
Indie games applying to GOG are reportedly rejected using a copy-paste form letter with a few words changed. The personalised feedback promised to users on the indie game submission page is not provided. In at least one case, it has been claimed that GOG did not look at the game's website or download it before rejecting it.
Con "Fair price" and DRM-free imposed
Great for consumers but posted here in cons on the assumption that more restrictive is always bad for developers.
