Five years ago, Supergiant Games unleashed the pretty much perfect Bastion - so they're having a Supergiant Sale!
That means you can nab both Bastion and follow up Transistor for mere chump change on Steam right now. Better yet double up with the complete Supergiant Collection and you get both games plus their rather spiffy soundtracks for a mere €9.68. And because Steam is awesome now if you happen to have picked up either title in the past, you'll get the corresponding discount.
Bastion is an isometric ish action RPG with some really slick gameplay and battles and wonderfully self aware narration which plays with how we expect stories to be made and followed. Transistor is a neon infused wonderland of singing and strange semi turned based combat. It's deadly.
The link for the collection is right here.
In case you need more convincing here's some trailer goodness.
