Mm, I'm just trying to figure out which Rune Factory to get. I've been trying to figure which is the best one but it seems they all have their weird faults.
I really reccomend Rune Factory Frontier. I played the game to death, logging over 100 hours just to finish the story (and I'm one of those people that sucks all the life out of a game as soon as I get it), and I enjoyed every minute spent. It does have it's flaws, but ot is definitely worth it. I think Crimm can vouch for me on this one seeing as he wrote the review.
Just as an aside, I have played Rune Factory 2 on DS, and I just couldn't get into it the same way I did with Frontier
