MonstaMunch: No worries. I'll keep the gift code for you in case you want it afterall, if not then I'll do a give away for it on Christmas ;)
etna87: I'm terribly tired right now, and might not be online much during the week (at least not at home, where I prefer do to everything that involves payment), but you can rest assured you will not be left with a Psychonauts key you can't use ;) (it is on my "must play some day" list. I have been holding off buying anything so far because of backlog and because I'm still somewhat annoyed at CDP for that law firm nonsense)
Though trading might be more difficult if nmillar's info in this thread is correct and buying+gifting blue coins on GG doesn't work (don't remember if your question to GG support was more recent).
Wow, thanks for this, that's awesome.
Regarding blue coins: You CAN gift them (FreshH gifted me some yesterday), but you have to gift them at the time of purchase, so you can't gift blue coins that you already have. However, you can use blue coins that you already have to gift games.
Thanks again :)
