Well not that much, as I already got it, but maybe. Depending on what you want.
Hmm... What would you be willing to trade, from your inventory? I would also accept 1 TF2 key + 2 refs for each copy.
The problem with that is that in my eyes 1 copy of Skulls is too few for Risk and 2 copies is too many for you I presume.
Especially because for some reason Risk is being largely sold for 2.5 keys, even up to 3 (sometimes 2).
One of us is going to have to add something for this deal. I might have given it more consideration 2 days ago.
I can throw you an extra Pressure / RIP Trilogy / Toki Tori / Natural Selection 2 in addition to Risk for 2 copies of Skulls.
You're right, RoR is worth more than 1 and less than 2 SotS. I just mentioned it because it was the one title I had interest in. Also, I don't have 2 copies anymore, probably not even 1 depending on an ongoing trade. All in all, you should probably look for a different trade altogether (I'm saying this in a friendly way).
Those are all serial keys and not gifts. From Amazon. I will not go first unless you have over 100 rep.
I've got Darksiders I, Darksiders II, Darksiders II Season Pass and all of its DLCs except for Shadow of Death.
With the exception of Darksiders I, I will not be selling them separately.
