Is Dark Souls really that good? Well, yes and no. Yes by comparison because I haven't come across a single game that does what Souls games do anywhere near as well. So it's not about Dark Souls doing anything especially well, just every other game doing the same thing poorly or not at all.
Dark Souls isn't mechanically all that difficult if you play a tank character. It becomes more about tactics than timing and mechanic skill. Even with a light character it's a lot more about knowing when to hit, when to heal, how to position yourself, being patient and cautious etc. than doing some crazy combos with insane timing or anything like that. Pretty much the fundamental thing about Dark Souls that separates it from the mass is how you should approach an encounter; in Dark Souls not getting hit comes first, then you start thinking about doing some damage yourself. In most other games you just beat on the enemies not getting hit or not having to worry about it.
