I’m on the fence about which is better. Portal 2 is an improvement, but also has its flaws.

Part of the reason I would argue Portal 1 was better is because it was so unexpected. I went in expecting “interesting puzzle game” which it is, but I did not expect to also get “excellent humor with strange horror vibes and incredibly good personality.”

If someone didn’t know what a Glados was I think the first one is better. I also recognize that many people who have never played Portal are well aware of Glados.
