Cant gift Anomaly: Warzone Earth cause its not on list ??

Don't make generous giveaways of games you picked up where anybody could get them for free.

It's free therefore it is HERESY!

If I recall right it was free somewhere so it got removed from the list.
This is to protect the site from people making hundreds of giveaways for the free copies they got which causes the site to slow down (and sometimes crash).

Try giving a different game, that might work.
As long it's not another game that anyone can get for free.

Cant gift Steam client cause its not on list ??

Ive never create any giveaway but now i couldnt cause this useful application isnt on the list :DD lolz
