I have never completed the platform game Portal 2, although I had it almost since its infancy in 2011. There, I said it. Anyway, I am all game to trying it out again, and this time I intend to complete it - on Linux. I forgot how much this game can be a fun, while solving puzzles in a dystopian world. It is quite humorous, too. How can you not enjoy this line, told by a giant female robot, GLaDOS, to our protagonist: "Okay. Look. We both said a lot of things that you're going to regret. But I think we can put our differences behind us. For science. You monster."?
You can listen to it here.
