An eclectic mix
Destructoid has taken some time to figure out how to handle it, and we now have a Curator page that you can follow if you so choose. The list is being maintained by several of us at once, so the only unifying theme for the list is “games that at least one of us really likes.” Currently, we are featuring titles like Samurai Gunn, Valiant Hearts, Electronic Super Joy, and The Swapper, and we hope to maintain the list and update it when great new stuff comes out.
If you do a search and happen to find the other Destructoid Steam Curator, that is the unofficial one run by the Destructoid community (which is responsible for Team Fortress 2sdays). The Mr. Destructoid group is official and curated by Destructoid staff. Both lists are worth following!
