I totally see your point. Things like that, and like how you get to the Ancient Stone Dragon. Who the frick would think there are two illusory walls? I didn't even know about the cave at DR Basin until my current playthrough.
However, once you do the DLC it makes sense that it is where it is. Still, a new NPC at Firelink to give you some sort of idea would have been convenient.
I think the best Dark Souls experience is to play it for the first time blind. No guides, no nothing. And then use walkthroughs, YouTube videos, and forums for hints and stuff for your next playthroughs.
Right, it is just odd to have to restart the game like that.
I happened to stumble on that cave while playing, which was a huge relief since the Hydra kept killing me. But I never would have thought to go look back there to find Dusk, internet told me that. Unfortunately I read so much about this game before I decided to buy it that I spoiled a lot of things. I can't wait for Dark Souls 2 b/c I won't be looking at anything until I play through it once.
I really wish I could go back and play Dark Souls for the very first time. I can't remember the last time a game just totally absorbed me like that.
