12. Skyrim
People have lost entire lifetimes to Skyrim by now, whether it be the average player putting in around one hundred hours, to those who are still gallivanting across expansive arctic tundras in search of a treasure-mapped-hint of wealth just on a whim. Skyrim is such a crowning achievement, it managed to take the gigantic ecosystem of previous title Oblivion and tie-in more modern instantly-rewarding elements such as Fallout-style kill-cams and a fun, rewarding level-up system. Devoting hours to its cause showered you with a laundry list of perks and abilities with which to more accurately let-fly an arrow into the noggin of whoever stands in your way. Then theres the world of Skyrim itself; a staggeringly impressive undertaking, the scope of which has only recently been matched somewhat by Grand Theft Auto Vs monolithically expansive city San Andreas. As well as this is the fantastical story of your character The Dragonborn, prophesised to bring about the destruction of the tyrannical dragons that have also arrived in the world, raining down destruction on all and sundry. Whether youre following the main quest line, siding with warring factions the Stormcloaks or the Imperials, or just picking a distant mountain before embarking on your own personal quest to see what sits atop it, Skyrim is a game so gushing with variety and customisation, it rivals Warcraft in its ability to allow you to completely live another life.
