John Patrick Lowrie and Ellen McLain are so close to Valve and have voiced so many of their greatest characters, it’s easy to simply consider them employees. This year was particularly great for Ellen McLain, whose voice work for GLaDOS in Portal 2 brought her near-universal acclaim and praise. Sadly, John Patrick Lowrie will have to wait until 2015, when he voices Odessa Cubbage’s son in Half-Life 4.
