It's pretty early in the year but so far I can easily say that Portal 2 is probably near the top of my list of 'Awesome games', it's hard to deny how fun the game-play and characters are. However, if you haven't played it... Stop looking at this and go play it. This contains spoilers.
More importantly though, if you've been longing for the ramblings of Wheatly, Cave Johnson or any of the characters, look no further.
This Portal 2 soundboard is a collection of lines from the game files - even some you didn't hear in the game! Again, if you haven't played the game, don't click the link. Go play it first!
Enjoy!
Trailer for fun:
This game is fantastic!
