For science

We finished the main storyline of Portal 2 a couple of nights ago, and I should say right now that there's absolutely nothing that I can say about it that isn't a major spoiler as far as I'm concerned. Even if I avoid the story entirely, there are so many elements that I really loved discovering entirely for myself - I especially enjoyed the Britishness of it, and the game has an odd sense of humour that rarely works in the genre due to the inconvenience of having to include the player in the script somewhere. I was pleased this time to get to the game before said game's legions of stupid fans on the Internet proceeded to ruin it - it was a new experience to be able to play through it without being able to recite the whole thing from collected fragments of text.

( So don't read any of this if you haven't played it! )
