Hahaha yeah right.
Portal 2 made the story better, the atmosphere was also great. It was better than Portal 1 imo :I
Portal 2's story was pretty much just an action story with portals involved. It was much easier than Portal 1 too, which also turns me off about it.
The atmosphere is stuff. It's just Aperture labs undergoing deterioration. It also wasn't creepy or lonely or anything like the first game because there was always somebody there to talk to you. Whenether it be Wheatly, Glados, Cave Johnson, Defective Turrets, etc, there was always somebody talking. The first game had only Glados talking. (the same person trying to kill you.)
But hey, it's my opinion and you've got yours. That's ok. You have your reasons.
