IGN - I already know that reviewing Dark Souls is an experience I'm never, ever going to forget. Putting in 10+ hour daily shifts on huge games isn't an alien concept to most people in my profession – but a game that's this dark, this punishing, this emotionally demanding? And – of course – a game this fist-eatingly, heart-achingly, soul-crushingly difficult? This is a whole other thing. Having spent 12 hours of the last 24 immersing myself in its world, Dark Souls is actually starting to affect my mental health.
