surfhick: I'm thinking about buying a game but I want to give the copy to someone else. I already have it. Can I dothis?
TanguyLOZ: Yes it is, you'll find the option to gift the game in the checkout screen, near the total price below. Since you already have it, it should be already checked..
Oh, yeah, I missed that. In that case it's instead impossible to NOT purchase it as a gift.
Maighstir: I think you need to purchase a game for yourself first, before GOG lets you purchase gifts.
Leroux: Since when? I don't think that's true.
Confirmation that I remembered correctly:

I cannot buy a game as a gift, why?
We had to implement some restrictions for buying gifts with some payment methods, for security reasons. We know this can be an inconvenience, and we're very sorry about that.
As stated in checkout, in order to gift games, you need to have purchases, worth at least $10 / €9.19 / £6.69 / A$13.99 / 719.00 RUB / 55 DKK / 70 NOK / 65 SEK / 30 PLN / C$ 10 / 10 CHF, made at least 3 months ago. Unfortunately we are unable to lift this limitation, but in some cases we might be able to help manually. Please contact us via the support form for more information.
