First, I'll give you something Dark Souls never does: a warning. Brought to PC by From Software, this port of the Japanese fight-heavy action-RPG is just that: a port. A straight port.
It plays like someone took an Xbox 360, packaged it up small, and slid it into your PC when you weren't looking. The HUD is huge, the textures muddy, and such luxuries as control over field of view and vsync are nonexistent.
Ask yourself how you pronounce 'PC game'. If your emphasis is on the 'PC', then run. Run far from Dark Souls and don't look back. There is nothing for you here.
There are many reasons to run. The twisted, shrouded, uneasy medieval fantasy land of Lordran stretches away like the darkest night. Go the wrong way, probe too deeply into the inky depths, and the things that lurk there will get you.
My best analogy: it reminds me of being six years old and hearing a noise downstairs in a dark house.
