Nothing really that big. I have some mental issues and some problems get bigger in my head.
In this page I tried for first time gifting a game as a steam gift. And two things happen that make me very worried. The first that maybe I couldn't gift the game if the price difference is too big,, and I didn't mark the giveaway to have region lock, and the second was that if the winner didn't show up for 5 days, the deal of the game of the giveaway would finish, and I would had to pay the game at full price.
I was panicking at the end, and started wanting to make a ticket about it, to tell them to give me the suspension soon rather than latter and that way have some peace of mind. But just at that moment the winner showed up, and I was able to give him the game without region problems.
I don't think I will give a gift trough steam again. I can think of one exception of a game that I really like and is cheap but I will have to learn more about steam gift region restrictions before that.
