Mike Sass worked at BioWare for twelve years. That's an astonishing amount of time for an artist to stay put at the one studio, but it also means that if you've ever picked up a BioWare game or even seen an advertisement for one, you've likely seen his stuff.
Working mostly as a marketing illustrator, Sass' richly illustrative and, dare I say, refreshingly old-fashioned pieces have helped sell and define our experiences with games like Baldur's Gate, Neverwinter Nights, Jade Empire, Knights of the Old Republic, Mass Effect and Dragon Age.
He left BioWare in 2008 to go freelance, and has since worked for companies like Blizzard and Magic: The Gathering owners Wizards of the Coast.
