Laggers: Unless gog is currently working on a patch, they are not fixing any issues.
"If, within 30 days after the purchase of your game, you experience technical problems or game-breaking bugs that prevent you from finishing your game, contact our customer support. They will do their best to help you fix the problem and if, at the end of their attempts to solve the problem your game is still not working, we'll give you back your money."
Nothing here states that a customer has to wait for a developer patch. If the game is unplayable and it's not the fault of something on your end or gog's (both of which can usually be fixed by contacting support) than you sure as hell deserve a refund. Nobody, except the devs, know when and if they will patch any/all issues. It's unethical to keep people's money hostage for an uspecified amount of time and against their own ToS.
GOG doesn't patch games--the game developer supplies the patch--GOG simply distributes it to its customers in the GOG format. What GOG is saying is: "Give us 30 days and if by then we cannot get the game to run in your system then we will refund your money." No, you don't have to wait on a patch, but you have to wait 30 days and work with GOG to get the game running on your system. If it so happens the dev releases a patch that fixes your problem in that time span then there you are...
That is much better, imo, than what Steam does. Steam gives you *two hours* of game play to request a refund and after that--no refunds for any reason--and generally Steam doesn't care if the game won't run on your system, and offers no direct help for the customer, etc. Big difference in after-sale support!
