Question for anyone with Harvest Moon games or Rune Factory games on their DS?

Well, as you said, there's pretty much ZERO fighting in Harvest moon. It's a Farming game where you plant seeds, plow fields, animal husbantry, etc. The only real point to the game is to get married and have children. It's basically just life in 1840... Rune factory has more of an appeal to... basically everyone, since there's an actual point to the game. But Harvest moon is fun when you're on a plane, or train or the subway. If I were you I'd just stick with Rune Factory.
