I have all 4 games, however, I can no longer play the original GCN one because my controllers broke. I constantly play New Leaf and have left the others in the dust, but City Folk was my fave game before New Leaf.
Also, if I can correct you on one tiny thing: The "insurance" in WW is not bought from Tom Nook. Lyle stops by your house every Saturday. It's a rip off too.
