You really want Wario, you gotta let Nook lick your wallet for a measly 10 something Nook Points a day(not counting the 3 visitor points). Bad boy stache and Wario hat both cost a fortune in points.
Don't worry, he'll ask you to change back once you've spent another 300,000 Bells or so. Choose 'Variety' if you want Nookington's to return. I've swapped shops twice already.
It's nice to have Nook n' Go around during the summer when you're out catching expensive, exotic bugs on the coconut trees(they only come out after Nookington's closing time). Nook n' Go will be open till 1 am :)
See, I wouldn't want to do that. In fact, I'm kinda upset I've already paid off my house - an immediate, useful reason to play every day does WONDERS to make the game last. I'm only about half a year in and I've virtually done most of the tasks in the game... and it has to stretch for another few years!
I still play it daily. Mostly just to finish one cycle of events in the game (a year). I've got my basement, so Nook's debt can go to pot for the time being :p I'm saving my money to get my town a lighthouse
