HookedGamers writes: "The clearest thing about 2007 is that, among the biggest triple-A titles that were released including, but not limited to, Halo 3, Call of Duty 4: Modern Warfare, Bioshock, Crysis, and God of War 2, few would have anticipated that a little tie-in title to a Valve box set release would garner such love. When the Orange Box was released that October, though home to the much anticipated Team Fortress 2 and Half-Life 2, Portal stood out far beyond either of them and gained both the love of gamers and a seat in the spotlight reserved only for a handful of games in history. The charm, puzzles, dialog, and amazingly fun gameplay was universally acclaimed in such a way that people were frothing for a sequel or, at the very least, an expansion within weeks of the game's release. Valve heard those pleas and released an expansion for the Xbox Live Arcade called Portal: Still Alive the following year that consisted of the full game and additional maps created from user generated content.
This however was simply not enough. Portal 2 was announced last month and, from all reports, it looks to be both a strong departure and a return to the familiar."
