Steam has a deal on _ICEY_. It's an indie metroidvania thing, and is less than ten bucks.
The game itself isn't the real deal here. If you buy the game bundle that is available until 10AM pdt on the 21st of this month, you can get a Steam Link for $1, plus shipping. Worked out to $16 and change.
Love mine. I hardly ever use it for gaming to be honest, but it is great for streaming a desktop to a living room TV for stuff like Youtube, Netflix, browsing the internet, or whatever. For games it works pretty well, I don't do it often, but it works well enough when I do. It can do wi-fi or a hardline. Mine is hiredwired into my network via an ethernet cable, which is the best way to go if possible.
Ordered this just to have a backup Steam Link for whenever mine finally dies. Mine still runs like a champ and I don't think it will die on me anytime soon, but I doubt I'll ever see a better deal on one.
