It might sound like a nice niche and interesting game to try, I was pretty pumped prior to release, but any "feature" in AC is hideously under developed, gimmicky as hell or simply downright broken.
Even with friends/family, even with the GBA, even with any crutch you could give it, Animal Crossing sucks and it sucks hard.
Simply put, the problem with the game is content, it very literally does not exist in AC's vocab. The entire game can be summed up as: a few fetch quests, a few NES games, a few sets of really tacky furniture and the "amazing ammount of characters and dialogue" in reality are 200 models that come and go as they please running off of 4 or so pre-set personalities cycling a handful of quotes. None of the events have any interactivity, etc. And in certain cases, it's pretty embarrasing.
AC doesn't even feel like a Nintendo game, it's so dodgy, there's no polish to the actual "game", and there's no hint of good design. It feels like one of those shody 3rd party Japanese life sims, only with a little more freedom to wander around.
Maybe it was impressive for the N64, but Nintendo can do a fuckton better. AC is just completely lazy work.
