So If I want to be technical I'd say Wild World but I was really stubborn and didn't want to read anything so my mom returned it the day after I got it but I have played it . Well in reality my first game was New Leaf.
Animal Crossing on the Game Cube was my first game and since then I've Played Wild World and ACNL. I almost got City Folk but then NL came out so I bought that instead.
Animal Crossing on the GameCube. My friend introduced it to me in middle school, and I asked my mom to buy a copy for me. She even started playing it too!
It was the lovely City Folk for me. I saw the game at the library and decided it was cute and I should try it out. After keeping the disk forever I returned it and my dad bought me a Nintendo Selects one.
I played Wild World--it was my first DS game and my favorite until I got Pok?mon Pearl, after which I forgot about it for a while--and got New Leaf for my birthday the year it came out (which was technically two days after it came out, lol xD). I've also played City Folk and it was the first AC game I've actually really gotten into, though I find NL all-around more enjoyable.
