Portal 2 is here and it outshines its predecessor in every way. The 2007 surprise blockbuster was only three hours long and came packaged with several other games in the Orange Box. The astonishingly well written and inventive puzzler generated memes for months to come and is still quoted today. “The cake is a lie” and Jonathan Coulton’s ending credits song Still Alive are plastered on t-shirts and are available in the Rock Band store. How could such a successful independent game get a sequel that would do any justice to the first game? Valve found a way.
