Well, the game is certainly interesting near the start of the game. Except for an excruciatingly long question sequence in the start of the game where you basically give a few simple answers that could have just been answered by a menu, you will immediately be interested in the seemingly massive world of Animal Crossing. There seems to be so much to see, get, visit, and earn.
After a few days, it gets old, and you lose interest. Who thinks it's fun to just run around, delivering different crap to lame looking animal-things?? Conversations will seem to go on forever, wasting time with pointless and amazingly lame jokes rather than just getting right down to business. Maybe you think it's great to wander around a small town, digging up random crap like dinosaur bones, and going through a long and painful process to identify them, but I don't. The features that this game has with other stuff like the gameboy advance is frankly window dressing. The "island" is not really any different than anything else except the fruit looks different, and the you have a beach house that you can store stuff you can't fit in your other house. Like I said before, conversations go on far too long. They will seem interesting in the beginning, but after a while, you just get sick of hearing the same pointless and idiotic dialogue time after time. The items you can get in this game are all, except for a few exceptions, just ornaments. They don't do anything, unlike the sims, where an item is actually USEFUL. Also, your character is too generic. No stats at all, unlike the sims, makes you feel like you have the same guy you started with 3 days ago.
The Bottom Line
I can't say I'd recommend it unless you have bought every other game, and are bored with those.
