Valve has another hit on their hands with Portal 2. The story, gameplay, graphics and sound all come together to make for a very polished game but it’s not without imperfections. Portal 2′s biggest downfall currently is it’s lack of replay value. As the game stands at launch, it’s a one time play through.
Any game that I can sit down to and get completely lost and immersed in until the end credits roll is a winner, and Portal 2 just as in Portal 1 had me from start to end. Valve has another winner on their hands here.
