The Cake is a Lie: Jumping into Portal after 10 Years

Seven years ago, I spent a lot of time immersed in the scientific experiments of Aperture Labs in Portal 2. I enjoyed my introduction to Valve's Portal universe so much that I still drink my coffee out of an Aperture mug, but due to modern consoles not having the game that started it all, I had never played the first Portal. Given my recent penchant for puzzle games (Gorogoa, Opus Magnum, and my own game that I'm building) and my discovery that so many amazing old games are on Steam, I thought it was about time that I finally jumped into what is generally considered to be one of the greatest puzzle games (and games in general) of all time. Could the original still hold up after all these years and my previous exposure to the much more refined sequel?
