Agreed and thank you all for answers. I guess I'm just being overly idealistic here. Change of question:
Is there a way to get rid of/delete the games that I don't want to see in my account anymore?
A weird question maybe, but I think many people bought at least one game that somehow ruins the overall warm feeling of looking at their otherwise flawless collection...

Well, I surely don't think any game ruins (or would ever ruin) my collection. Even if I don't play as much with a game as I thought I would, I don't despise it being on my shelf. Of course, you may have a different attitude.
There is no such way. However, you could try contacting the web support team, explaining you feel this game is just not for you and you feel your shelf would be a better-looking one (more reflecting your personality) without that piece, and maybe pointing them to this thread, saying that you've really tried to find a "normal" way of getting rid of said game, and after all this, asking them to make an exception for you and remove the game from your account. This way, they should be sure you're not retaining any spare executables.
That said, I can't promise wonders; it may be that they simply don't have the authority (I doubt it) or inclination (more likely) to do so.

Wow this is weird : ).
I have 70+ games on my shelf with no intention of ever playing 30 of them maybe, but I am still happy they are there as a proof of my liking of gog : )).

Hi Pavle,
I believe that proof of liking GOG is in the amount of money you spent through their distribution system not the actual resulting image of your virtual shelf, which, just like my actual shelf, I like to have neat and tidy. Don't get me wrong, I love GOG with all my fingers, but still, once I purchase retail or GOG game I don't really like afterwards, I don't want to keep it around. I either give it away or discard it. I was born with this defect and there's nothing I can do about it. That's my whole reason for all this weirdness :) And I now really think this is all too much trouble to go through just to tidy up my virtual shelf.
@DrIstvaan - If you like all games you buy, you're a lucky guy. Although I try to read reviews before purchase, it happened to me many times that I bought a game that didn't fit me.

I don't say I like every single game I've bought; there are some which don't fit my style as much as I thought they would, or I need more time to get into them
What I say is that I even keep there games, because I think my shelf looks better with them on it.

Ok, I kind of understand : ).Each to his own : ).I doubt gog will introduce this tho'.
