So this is something I used to do with one of my old teams when I worked in the industry, and it was always a huge hit. Every year, we’d do a Steam Secret Santa. It worked as follows:

• in December, participants would fill their wishlist with at least 12 games
• participants would share their Steam IDs with each other, and each of us would draw one ID each
• when the Winter Sale started, we would check our recipient’s wish list and buy them a game from it, to a set maximum value (we used to go for €20, but with the Steam Sale you can easily go less)
• We would set the delivery time for 00:00 on Christmas Day

So what does everyone think? Would this be something you’d be interested in as a community? If there’s enough genuine interest I’d be happy to try and coordinate something using an online service like Elfster.
