My very first experience with Steam Gifts

had the same experience like you. happens NEVER again to me. so sad that such people exists :(
I think that was a lesson we learned here ;)

You tried to trade a game that's worth 5$ for one that's worth 10$
¯\_(ツ)_/¯ if a deal is too good to be true then its a scam

I love everything people sent me, but guys nobody died I still got Space Engineer wich is a good game :V
I only paid in total 5 bucks... It's fine, me parents told me not to make fun of autistic people.

Oh yeah, always double check the link they give you. Click on the "Visit Steam profile" button and see if it's his account. Otherwise never go first.
Plus, once he's in your friends you can check his rep on steamrep.com, because he will be there by his unique user number, not fake impersonator name.
