Antichamber vs Planetside 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!
Planetside 2
Planetside 2 is a sci-fi-themed MMOFPS game that's the explosive sequel to its predecessor, Planetside, which was released back in 2003. In a way, the game is more inclined towards the extravagant and yet is still rather down-to-earth mainly because it features massive battlefields where hundreds to even thousands of players can battle it out for their faction. In fact, the game has an exciting gameplay which may bring to mind the games in the Battlefield franchise albeit the futuristic sort.Not to mention, Planetside 2 has an actual war playing out on the map where players who won a certain battlefield will essentially "claim" the land for their faction. The tug-of-war-like power struggle between factions help to bond the players in a way that resembles the deep rift between the Alliance and the Horde in World of Warcraft. The game is also developed by Daybreak Games which is in pretty good company along the likes of EverQuest 2, DC Universe Online and Lord of the Rings Online.
So, if you're looking for an epic MMOFPS game to fully immerse yourself in, then Planetside 2 is your best bet. If not, there are plenty of other casual shooters out there, but you can definitely expect that none of them can measure up to the faction-vs-faction tension, which usually erupts into another battle, offered in this game.
