Can the sequel possibly live up to the original?
As most gamers know first-hand at this point, Portal was an absolutely fantastic game. It combined a great new mechanic with innovative puzzles, a strong story, charm and an extremely strong main character. The magic of Portal didn't lie in just one of the elements, each and every part of the game played into why it was so enjoyable. This, in essence, is why I am worried about Portal 2.
