Excluding a few bumps along the way, Valve has largely won the hearts of gamers everywhere. The developer has delivered one hit title after another and its online distribution service Steam is immensely popular. Despite the success of its previous games, Valve says Portal 2 is the best yet.

In a recent interview with 1UP, Valve's Gabe Newell said the upcoming title is internally accepted as the best game the company has ever developed. With a portfolio including Half-Life, Team Fortress, and Left 4 Dead, that's saying a lot, and if you weren't already excited about Portal 2, you should be now.
