Antichamber vs Spore
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!
Spore
Spore is a pretty unique and addictively fun god-mode-like sandbox game where you get to create a whole new world and fill it with your living creations. As a "god", you can play around with the game's five evolutionary stages, from Cell to Space, and grow an entire space-faring civilization from its very simple beginnings as a single-cell organism. Of course, to develop a civlization, you'll need plenty of tools to help them along and Spore gives all of that to you in an easy-to-use format. You can literally customize everything you like in the game ranging from vehicles that your creations will drive or even buildings that your organisms will live in.Although Spore is essentially a single player game - after all, there can only be one almighty god... and that's you! - the world you've created is shared with other players in the game, so your creations can actually explore new planets and maybe even bump into a hostile race which will force them to make the preparations needed to go to war.
Overall, Spore is an amazingly detailed, civilization-building, sandbox game that allows you to micromanange almost everything if you choose to do so, or you could lay down the groundwork and let things unfold by themselves. Best yet, there is no limit as to how many worlds you can create, so unleash your creativity and your godly powers and develop the ultimate civilization today!
