Or it's just one person being overly impatient. Two days is nothing.
Or it's just someone who wants at least similar level of service to the competition, I had a choice between this site and the other one that has better service, and I chose this one just to support it, and I know many people do the same for the same reason, just for it to be at least on par with the competition someday, not for it to stay at the same level as it is in now.
If GOG picks your "it's just one person" mentality, it will stay where it is, a distant second, if it's even in second.
I just got notified that Grandia II has been updated; a 3 MB patch is now available for download that patches the game to version 1.02.
