When Valve released the original Portal as a pack-in for The Orange Box, no one knew it would outshine their main bet, Half Life 2: Episode Two. But the promise of cake and an ever-loving weighted companion cube overwhelmingly resounded with gamers everywhere, and new Internet memes were popping up all over the place from this mostly non-violent shooter-puzzler. Portal won numerous game of the year awards, and a sequel was announced a few years later. With such an outstanding release the first time around, did Valve deliver another diamond in the form of Portal 2? You bet your cube-loving butt.
