"One guy we should definitely mention too, that Max still works with to this day, is Matt Uelmen. He did all our sound effects and stuff back in the day, too. He came on early, maybe our fifth or sixth hire, even though we weren't sure we even needed a sound or music guy. But he kind of hassled us so much that we finally hired him, and he's just a great guy to work with, and we still work with him to this day, at least at Runic. Just a brilliant musician. Usually the smartest guy in the office on a lot of topics. But just also the classic music guy. He has a lot of eccentricities and personality quirks. He was also an incredibly good tester. He could figure out how to exploit or break your game better than anybody."— Erich Schaefer(src)
