Man, select them all, the entire list, not manually one by one, and select GIFT TO; enter your email that your gog account is tied to, and there you go.

Mhm, I still don't get what the problem is... you already own 2 of these games?
Then they should be listed under "items you already own" (on the bottom, greyed out), they shouldn't count to the total, so no need to rebuy.
You should definitely get the 90% discount. Do you really have them in your library, or just sitting around as gift codes somewhere?

Oh, okay, now I understand what he was saying. Yeah, this is a very good question. Make sure they're in your library and if they are, when you click on the Nordic sale thing on the front page, all the games should be broken down into two separate groups. At the top, all the games you don't own, and at the bottom, the two you do. If you click "Select All" at the group at the top, it should automatically select all of them and give you the 90% discount.

Yeah, like the two posts above this, I was wondering what you meant by "my library", too. If you meant that you own them (not as codes, but as games on your GOG game shelf), then, yeah, that's a bug, and you should contact Support. If "my library" meant "collection of all games I own in any medium, from any store", then you'd be better off doing as ThePunishedSnake suggested earlier, and just buying the entire bundle as a gift code, redeeming the ones you want for yourself, then trading (or giving away) the games you don't want/already own elsewhere.

There's a Pdf the game links to when you click on 'manual' in the game. There's also a wiki.... would you like me to direct you to the pdf so you can do a simple right click and save?
edit: oh no hang on, they actually decided to make it a separate goodie to download straight from your gog account... making it that minuscule amount easier.
edit again!: my bad I thought you were asking for it.

OFG, you ARE still around! *wavies* Merry Christmas to you~!

Can't you find the manual(s) somewhere online?

I hoped I might be able to help you out with the missing manuals, but it doesn't look as though there was ever a manual for Raven.

Good to hear...
That's quite a backlog you've got yourself there, with just one purchase ;)
