If you've never played Animal Crossing before, I really suggest that you try it out. It's really in a world of it's own, it's like a vacation from traditional video games, while still providing the core essentials. It sounds strange when being explained, but when you play it... it's just... a fun game. I mean, planting trees, making friends, collecting furniture... it doesn't sound very compelling. But once you play it, you'll start to really enjoy being in the world of Animal Crossing.
