All except the Japan version. I played wild world a little bit, but not for long. I did not like that one at all.
I still play the GameCube and wii version.
I've played all except Dobutsu no Mori e+ and City Folk. CF came out when I was in HS and I just wasn't really interested in AC anymore. I really love NL though and I'm really glad I bought it.
I've only played the GC one and NL. I wasn't even planning on playing NL but I kept seeing it all over tumblr and my friend kept talking about it so I gave in, and I'm glad I did.
I've played all of them except e+, I never really got too into WW though, the towns just felt really bland, the only thing I liked was how much dialogue the villagers had.
