"There are many other things to do in Rune Factory, such as fishing and mining. The townspeople are more than happy to sell you expensive items. The most you will buy is probably seeds, but you can also extend your house, build monster huts, buy equipments and even spells. And on holidays, you can purchase household items from a wondering salesman.
But what would a Harvest Moon game be without the girls? There are eleven girls in the game, and by extension, eleven potential brides (no, you can only marry one, and there is no such thing as divorce, either). Each girl has her own likes and dislikes, and it's up to you to wow them with your charm and gifts. You are not much of a looker, so give them gifts to win their hearts. To ask her hand in marriage, though, might require a little more work. You might be asked to fulfill a certain condition before she would consider becoming your wife.
If you managed to score yourself a wife, and have played the game long enough afterwards, you will eventually have a kid. No getting naughty in bed, no pregnancy, the cute little baby just pop up one day, never to leave your wife's arm. And that, my friend, is your ultimate goal of your life as a farmer-cum-warrior. You can continue to play and play and play until Rune Factory 2 hit the stores."
