I performed a quick search of the forum to see if this had been mentioned but found nothing.
Broken Age is available at Walmart, Amazon, etc. Walmart's price is, on average, 8-10 dollars higher than elsewhere. I purchased the UK version which appears to be the same as the version I saw in Walmart. The package reads "No DRM" and "Steam NOT required".
Since there is such a paucity of physical games nowadays, I though I would post it here. Feel free to delete this post if this info has been covered.
