Jeffrey Matulef writes, "I'm not sure there should be a Portal 3. This isn't a diss to Portals 1 or 2; quite the opposite. Rather I feel like Portal 2 ended on such an impossible high note that following it up with, well, anything sounds like a fool's errand. Then again, I said the same thing about the first Portal before Valve blew me away with its sequel three years later. So if they DO decide to make a Portal 3, here's what I'd like to see put in it."
