Still a very enjoyable series but just Wild World with a update pack.
The enviroment is pretty cool though because it's split level. It does have a glitch in the grass so that it can dissappear if you upload the game to many times or visit many peoples town via Wi-Fi. It can end up looking like a desert if you don't lay patterns down. If you do you'll end up missing out on fossils and breeding hybrids. It's a problem that can be irratating but only affects you if you care about your town appearance wise.
The characters really haven't changed very much. The only addional side quests are Hide & Seek and to occasionally fish out a key from the river. Triggering the events is still random and rare.
The furniture sets at Gracie Grace are new and very pricey. You'd have to accumulate over a Million bells just for one set. There pretty awesome though. I really like the sweets set it's modeled off of pastry and candy and the gorgeous set it's sophisticated with gold, black and red theme colors . It's just that it's seasonal so you have to wait a year to get them all without Time Travel.
Overall the game is very cool even if it's Wild World with a update pack.
