They made it WAY too annoying to get Spiritomb early.

Dang I was just thinking this earlier. I have 43 hours logged right now and probably at least half of them have been spent underground. I'm at Snowpoint, so I've explored four out of six areas in their entirety. And I've still only talked to somewhere between 22-28 unique NPCs. It's kind of ridiculous that it's actually harder to get Spiritomb here than it was in DPPt (it was mostly just tedious then, not to mention you could do it as soon as you got to the Hallowed Tower).

Is there a complete list/chart of all the NPCs' names and where they usually appear? I feel like that could make things a lot easier (or at least less frustrating) if it was possible to just see on paper which ones you haven't spoken to yet.
