Trying to buy a copy of the game for my friend.

[Naonode]

I'd like to buy my friend a copy of the game for the PC, but there are questions on whether I'd be able to just gift it to him on steam. Anyone got any recommendations on how I can buy him a copy?

Sorry if the answer exists somewhere for this, I've been looking but not finding it.

Edited in: To clarify, I'm fine with gifting it to him on steam if that will work. But it's a little unclear whether it will. This isn't a request for if there's some third party site or something. I'd like to buy an actual official copy. I realized my request could have been read the wrong way.
