Game cube was my first, I would spend hours and hours playing it. I remember my first town name, I named it after Arizona. I'm pretty sure I misspelled it, but I forget how I did. I joined TBT after I got WW, though.
ACNL. I was introduced to the game by my fiance and I have been hooked to the game ever since. I got the game during Christmas season so it's almost been a year now. Lol.
Game Cube! I had two towns on two different cards so I could travel back and forth. I still pop them into my Wii once or twice a year and go say hi to everyone (TWIRP 4 EVER). More than I can say for Wild World...I don't even know where I put the cartridge. That town has to be a disaster. I still pop in on City Folk too. I'm always freaked out by my CF mayor who looks like a little stubby gnome version of my NL mayor!
My first was New Leaf a few months ago. I've never really had an interest in the series and actually avoided it like the plague. Not sure why I bought it at all, but I'm glad I did :3
Wild World c: I have so many fond memories of that game. I had it on an R4 ds game and I had 4 characters c: my town was quite cool with paths and loads of flowers but then my favourite villager, Goldie moved away and everything went downhill and I stopped playing for ages. Then my R4 game broke and I got a new copy.
My first was WW. Can just remember the amount of time I used to spend playing it with my cousin. I could honestly say that I was even more obsessed with WW than I am with NL right now.
