Isn't Dark Souls a JRPG? What does that have to do with Zelda?
Its not a jrpg. Its a very atmospheric dungeon crawler that offers you deep combat mechanics against merciless enemies that can 1 hit kill you if you dont master your defense/evasion/attack skills and their patterns.
And by "dungeon" I mean rather straight forward designed levels or regions where most roadblocks are simply enemies you're not skilled or leveled enough to kill and progress through.
Does that sound like Zelda? Yeah...
Its in my top 5 favourite games this gen (though Demon's Souls is a bit better IMO), but it is NOT a Zelda-like experience. It might make some people feel as satisfied as they did when they played LTTP or whatever, but it doesnt mean they are anything alike.
I do highly recommend it though. But I do it for what it is, and Zelda it is not.
