Portal 2 Turns 10

Today marks the 10th anniversary of the original release of Portal 2 on April 19, 2011. It was released just after midnight EDT, so it was released on the 18th for those west of here. Either way, here's to a decade of puzzles, Wheatley, and of course, potato batteries. I'm sure there's some cake around here to accompany the celebration. There are tweets with some photos looking back on the game from Erik Wolpaw and Josh Weier (thanks GamesRadar+). Portal 2 has a score of 95 on Metacritic and is rated "Overwhelmingly Positive on Steam based on over 193K reviews. I'm making a note here: HUGE SUCCESS.
