If you know what dark Souls is then you probably have more than just a casual interest in games. While the rest of the world drools over Battlefield 3 and MW3, Dark Souls rewards the diligent with an amazing world, combat, customization, and level of accomplishment that can only be felt after hours of frustration.
In a era of soft games Dark Souls refuses to coddle the player. From Software assumes two things: that you know your way around a controller and that you can figure things out for yourself. And it's this tough love approach that makes this game so rewarding. Every minor victory is that much sweeter because YOU solved it instead of being told what to do.
This game is not for the weak and most anyone to their limits. By putting high value on patience and diligence Dark Souls challenges you to stop and think.
