It's a little bit strange in this day and age to see a PC/Mac-only game getting its own TV commercial, but you can get away with that sort of thing when you're Diablo 3. The long (long loooooooooong) in development lootfest RPG is finally coming out on May 15, 2012, and this new TV spot nods to that fact.
There's no gameplay at all. Let's be honest with ourselves here: the brand of top-down point-and-click RPG gameplay in Diablo 3 isn't exactly "TV pretty." Instead, the TV spot flashes between a series of pre-rendered cutscene shots that highlight the return of the Lord of Terror. Which character class will you be using to bring him down?
