Anecdotal, but I completely agree that Portal supercharges your brain, and I've believed this for years. Back around 2011 when portal 2 came out we had a family reunion. I had been playing a lot of Portal at the time. One of my uncles broke out one of those brain teaser type metal ring puzzles where you have to pull the rings apart. It made it's way around the room as we talked and no one could figure it out. As soon as it came to me, I saw clearly exactly what needed to happen to solve it, and within seconds it was solved. I still think it must have been all the Portal 2 I had been playing.
