Why did it take me this long to get around to playing Portal? It's a simple download, not too horribly many Live points, and I don't think I've heard a bad thing about it. So why did it take me until now to play it? I don't know, and it doesn't really matter at this point, because I've played it, and I loved it. It took most of my first run to get the hang of thinking with portals, but I think I've got it now. My second run took a whole hour off my first, and I got through Portal 2 without too much total bafflement. Yes, GLaDOS and the companion cube and everything that's been quoted to death, but the big thing for me is how incredibly satisfying it can be to solve a tricky test chamber. I kind of want to play again right now.
