Giftable copies of Total War games I own if I purchase the Total War Grandmaster Collection.?

Don't think so.

NO

No, steam never does this.

nope.bik

Nope. I already had Vikings: Battle for Asgard and I also purchased the Total War Grandmaster Collection from GMG a few months back when they had a sale on it. It was a single key and if you already had a copy beforehand, it's wasted.

I dont know, but I had 3 of Serious sam games, then I got Serious sam pack and after instalation this pack I got 3 x Serious sam (which I had already before) in my inventory as a gifts.

I wouldn't think so. The only games I've had this happen is Portal 1 and 2 (from activating the valve complete pack) as well as poker night as the inv 1 (from activating the HiB)

Nope, valve rarely does this and generally only with their own games

Okay, thanks guys!
