Antichamber vs Portal 2
Antichamber
Antichamber is the sort of game you'll want to play if you have a strong appreciation for MC Escher's mind-bending worlds and you have always imagine what it'd feel like to be in one of these worlds. Being an almost impossible puzzle game where hallways wrap around each other and spaces rearrange themselves, the game aims to push you out of your comfort zone and make you question how the game work (Hint: there is no permanent set of rules in this game and eveything you know can be changed). With your trusty gun in hand, you will need to create, destroy and manipulate the very matter itself to solve the puzzles you get and move on to the next stage.Antichamber is a puzzle game that's unlike any other. If you enjoy getting your mind blown wide open, this is the type of game you'll want to play... guaranteed!
Portal 2
Portal 2 follows in the footsteps of the award-winning original while continuing the story of Chell and Glados. Now with both single player and a 2-player cooperative mode, Portal 2 ramped up its game with a plethora of new, challenging puzzles, a storyline that's a lot richer than before, and more advanced and realistic physics that will govern your gameplay. Interestingly, the game also includes editing tools, allowing players to create their own puzzles which can then be shared for all to enjoy.Portal 2 is definitely a much better game in the series and if you fancy giving this franchise a chance, you might want to jump straight to Portal 2.
