This game is so much more than its original. The portal gun remains one of the most well designed pieces of gaming ever created, every puzzle feels challenging yet rewarding, and most importantly incredibly fun. Not only this but its story is guns blazing too. with only 3 characters to interact with it manages to pull off some surprising emotional beats. GLaDOS will forever be a favorite in terms of villains in general. Valve also knocks it out of the park in terms of atmosphere. Nothing can compare to the deepest most desolate parts of Aperture Labs.
