This week, we hit up five of the best games that we think we didn't talk enough about in 2015; no super deals, no hype or hard sell, just pure gaming excellence for GNU/Linux that you might have missed. "Galak-Z," "The Magic Circle," hell, we got something for everyone (we are including "Universe Sandbox2," after all, lol)... These titles, plus two other excellent must-plays of 2015.
