Ubivis: Or just create a new one and start from the beginning :)
No no no no no, this is my Good Old Account XD
Aningan: Contact GoG support, and since I doubt they will be inclined to delete games you payed for they might help with an account split maybe. Would be your best bet, but don't count to much on it.
I think that this is the best thing I can do.
Leroux: Actually that's something I've often thought about, too. I mean there's probably no good reason for GOG why they should remove the games from your account or why you should have them removed but all common sense aside, I have a few titles I don't even like to look at either (one of them I didn't even choose myself). Some better options to sort your games shelf, maybe hide some games from view or put them on a different rack, that would be pretty cool.
Definetly, this would be a cool feature.
Thanks guys!
