It's pretty good, but slightly lacking.
There's lots to do in animal crossing, from running errands for neighbors, to saving up money to pay off a debt, to visiting the city, to just plain fishing. You'll always be busy, but the nicest thing is that there is no time limit, and no pre-set goals. Just take your time and do whatever you want. Although the main goal is to pay off your house. Another nice factor is the ability to customise almost everything. Like you clothes, shoe color and appearence, hairstyle, headgear, furniture, and the amount of trees, flowers, and other things in your town. Plus, there's lots to collect, like different species of bugs and fish, as well as fossils, and the very rare paintings, and collecting them all can be quite satisfying.
Your town, (you can name it anything you want, and the layout is randomly designed) is just one of the places to go. The new feature here is the city. While rather small, there are some shops, and plenty of people to chat with. There are even a few secret areas and things in the city, (nope, your not getting it out of me!). You can also visit other friends towns via Wi-FI. (The part that bugs me are the insanely long friend codes)
While it is a great game, it does have some minor downfalls.
-it's nothing REALLY new, sure, some new features, but not much.
-It's the same thing as GCN and DS, no new goals.
-some things your neighbors say can get REALLY repetetive.
-graphics are slightly dated.
So, let's see the score:
Graphics: 7/10
Like I said, it's a little dated, I know it's supposed to be cartoony, but still.
Gameplay: 8/10
Like I said, LOTS to do.
Replay value: 10/10
It's IMPOSSIBLE to do it all in one sitting, it'll take at least 30 lol.
Stress factor: 2/10
It's soooo layed back...the only stressful parts are when all the shops close and your pockets are full.
Fun: 8/10
It can get boring at times, but good fun and lot's of stuff to keep your hands full.
Overall rating: 8.5
Animal Crossing: City folk has a lot to offer, and it's a lot of fun, but it just seems to be lacking.
Thanks for reading!
