I got DOZENS of TF2 chests going back at least 6 years, and have refused to buy a single key to date.
Funny ppplz don't even want to trade anything for a "relatively rare" munition crate or cos-case.
This should be a warning sign to Valve, but nuuuuuuuu.... they will just keep pumping out the Next big Thing.
That being said, Steam still runs circles around Origin or any of the other proprietary circlejerks out there with complete SHIT for titles.
YEAH, LOOKING AT YOU EA, BLIZZARD!
