A lot of the [Portal-specific] points you've made were exactly what I was thinking. I felt that the charm of Portal 1 was that the back stage areas were not intended as tests for Chell. Portal 2 is just "Do tests. Do more tests. Do even more tests. The End." Sure, there were the transitions, but the majority of the game is spent in Aperture's intended testing area. It's like if you went through all the chambers in Portal 1 and then saw GlaDOS at the end looking over the fire pit where she tries to kill you and that was the end boss battle. It's ultimately not as satisfying. Still looking forward to one of my friends taking on the co-op with me though.
And of course, it's very strange that GlaDOS has the potential to manipulate everything now, whereas before she could only send turrets and those eye ball missile launcher things at you.
