What? Are you suggesting the Sims was a rip-off of Harvest Moon? That's the dumbest thing I ever heard, Harvest Moon focuses more on farms and farming, while Sims focuses more on the actual people you're playing and just human life. You do realize life sim is a genre itself, and I'm pretty sure not every game in that category is a Harvest Moon rip-off.
Anyways, I liked the original Harvest Moon, and Harvest Moon GB/C was all right. Didn't care for anything after that.
