I'm not playing the game, but does Gamespot update its review score in addition to the review? It does suck because more than likely the review score is permanent and even if it isn't, it's unlikely that places like metacritic will update it. Given that from a practical publisher perspective, it's easy to see that side.
I can also see Gamespot's side, if they publish a review that doesn't reflect the issues, they'll hear it from site users. However, Gamespot has already tarnished their reputation, so I'm not sure what they are saving. It seems like the best solution would have been for Gamespot to contact Stardock about the issues and potentially post pone the review for 24-48 hours. Was a release day review necessary for Gamespot?
It sucks also that much of this problem is caused by pirates and it sucks to have Stardock and the Demigod developer penalized for taking a progressive stance on DRM.
