Nah, you buy a house, furnish it, talk to the neighbors (all animals), pay off your mortage, go fishing, dig up fossils..

It's like the Sims, I guess, but a lot better. (And there is no Bladder Meter)

Though, you can just chop down all the trees, trap neighbors with Pitfalls, beat them with nets, write them nasty letters, etc. (Though, they are unable to read those letters, it's funny to get a reply like "I loved your letter! Here's some fruit I found.")
