10 Ingeniously Clever Video Games That Will Mess With Your Mind

7. Bioshock Infinite

Marginally less lauded than the original game, Bioshock Infinite is nevertheless a masterclass of video game storytelling, and the medium's abilities to tell powerful stories about human history, politics, and unthinkable astrophysics theories.

Set in a skybound version of prosperous America at the turn of the 20th Century, Infinite combines a commentary about the country's relationships with religion and just how bloody highly it thinks of itself (i.e. exceptionalism), with a time-travelling romp based on the multiverse physics theory. This being the idea that infinite universes exist out there, based on every possible combination of things that happened in all of time. Got it?

As you follow the godly-powerful Elizabeth - who you're ostensibly supposed to be saving - through tears in the space-time continuum, it's easy to lose track just in which of the game's many universes you are at any given moment, what are these 'constants' and 'variables' that you're supposed to look out for, and what's with those Lutece twins popping up all the time with their synchronised rambles?

It all comes together beautifully in the 'Sea of Doors' scene at the end though, as you travel through various junctures in Booker's life, leading eventually to an ending that poignantly loops around right to the beginning - before it all started. Still don't get it? Then play this game immediately!
