i have an original 3ds that i've had since the day it came out. it's had it's good and bad days, including scratches and normal wear-and-tear, but it's still in decent condition.
my brother has a new nintendo 3ds xl and so when he isn't using that, ill sometimes grab it and put new leaf in there. the bigger screen is so nice... i've thought about buying a 3ds xl or a new nintendo 2ds xl, but the only game i ever play is animal crossing and it isn't worth that much money imo.
and also new horizons is coming out soon so i might as well stick with my o3ds now lol.
