The first three Rune Factory games are available for DS! Just a head's up, if you decide to try RF and/or RF2 you may find both to be rather dull at the beginning, particularly because the main plot doesn't start until after you get married. RF3, on the other hand, starts the main plot at the beginning. In my opinion, RF2 is pretty good if you can get to the main plot, but RF3 is the best of the three overall!
