I played a little bit of Wild World when my boyfriend didn't want to (the music is fantastic). New Leaf was my first AC game. I also have Happy Home Designer and amiibo Festival. My boyfriend has the gamecube version which I think I'll try out sometime from curiosity. XD
I've been playing them all since the Gamecube; I've loved playing them all since then, despite their ups and downs. It's nice to see what gets changed or added with every release, though sometimes I feel like replaying the old games either because of the music, layout or events that used to be in them (in some cases, how they used to be handled).
Currently I've been playing HHD and amiibo Festival and I have to say, they've been really fun even though they're spinoffs and not the next main game I had been waiting for. Both of them have some pretty cool stuff that I'd just love to see in the main games soon.
Also throwing in Animal Forest (N64) and Animal Forest e+, even though I didn't get to play those much since I don't understand Japanese. xD"
