I still have no idea why you just don't at least create an account though. It takes all of 2-3 minutes and then you can set it up if you want to at least get email updates about sales. Who wants to wait six months for a deal or have to pay full price for something you could have gotten at a cheaper sale price had you signed up now? Plus, are all of those unplayed Steam games up to the high standards of many of those fantastic GoG classics?
I find it to be a fantastic complimentary service to Steam. Almost all of my 55+ GoG games I bought on sale, I only regret maybe 3-4 purchases, the rest have been brilliant. It is worth it now, especially if you plan on signing up later on anyway.
Hope you don't mind my overly enthusiastic comments, it has just turned out to be a wonderful service and experience for me as a gamer, despite that really disappointing "we're shutting down" PR mistake. Just bought Ultima Underworld 1+2 and Dungeon Keeper at release, well worth the non-sale price, I will do the same with the upcoming EA releases Crusader: No Remorse, Sid Meier's Alpha Centauri and Magic Carpet! Can't wait to get into Dungeon Keeper tonight.
