Ah, the Steam Summer Sale: a week to remind you that you never really had any intentions of going outside, even when it was nice out. If you’re irresponsible with money — lookin’ at you, kid — then you may want to hide your credit card. But if you’ve been patiently “waiting for the next Steam sale,” this is your moment!

Every year, Valve adds a fun minigame to its sale — whether it be collecting badges or some kind of trading-card-palooza. This year is no exception, since you can now “fight the Duldrumz” in a new minigame. This will of course net you some trading cards. I guess it’s true what they say about Valve making games again.
