I also remember how much fun it was that the whole game was kept simple and each level was pretty much a tutorial leading up to the final showdown. If you disagree, then you have not truly played Portal. Every "test" level was just showing you how to use your gun and how to chain things together.
So after all that nostalgia and the huge announcement at the Sony Press Conference about GLaDOS' taking over of it for a short moment, it was solidified that I was anticipating Portal 2. Who wouldn't be after all of that? In fact I was so excited that for it that I have been constantly hunting down any new video for Portal 2, finding a load of videos showing off all of the new features of the game that Valve is putting in. I've listed them all below for your viewing pleasure.
Before you watch them, I do have a bit of a concern that I want to share. It looks like Valve has taken Portal 2 and made it a truly full game, leaving behind the original "mod" feel to it. Which could be good right? Maybe. Maybe not. I mean looking at how these test below are played out I can see more frustration than enjoyment. Leading to an increase in Tourettes in the AggroGamer house. At least the humor seems to be there to lighten the mood.
