Okay, I can finally spread light on this. I had the shop in my NA town- not the tent the shop. I visited my NA town with my JP town everyday for 3 weeks, making that 21 visits total. When she showed up in that one, she did NOT request a shop. She did however after she showed up again about a week later, but then I repeatedly made villagers, visited, killed them off, made more, visited, killed, etc, until I was at 19, then had my mayor get his fortune read after they all had. Guess what, she requested the shop then. I got her pretty quick in my NA town by simply having 4 fortunes read by all 4 "players", but I'd do it in reverse order, the last setup was the first to go, so the mayor would be the final of the day, because I'm pretty sure she only requests it to the mayor since the others have no say in PWP's, and 20 is divisible by 4. Not new to the game kind of makes me think about little things like this!

In fact, it was because of the original and Wild World that I began making 3 more players than me- gets me money faster, holds more items for me, etc, etc.
