My favourite has to be "Rune Factory 3." I fell in love with this game 2 months ago and would play for 12 hours straight (with bladder and meal breaks, of course.) A friend of mind introduced this game to me and he says that it's a farming game similar to the harvest moon games I played and loved when I was in high school. But, it has added features like adventures, quests and my favorite, monster bashing and collecting monster items. I finished this game in just 5 days. It would have been finished earlier, If it wasn't for work and all. What's your favorite game in Nintendo DS?
