Yahtzee: Lastly, there's Portal, and if you're a regular viewer you'll understand how insane these words feel coming out of my mouth, but I can't think of any criticism for it. I'm serious, this is the most fun you'll have with your PC until they invent a force-feedback codpiece. I went in expecting a slew of interesting portal-based puzzles and that's exactly what I got. But what I wasn't expecting was some of the funniest pitch black humor I've ever heard in a game. OK, it's only two to three hours long, but that's a good length for it, it means that it doesn't outstay its welcome, and it narrows the gap between you and the balls-tighteningly fantastic ending. Absolutely sublime from start to finish and I will jam forks into my eyes if I ever use those words to describe anything else ever again.
