Final Fantasy, Ys and Dragon Quest are the biggest selling JRPG franchises in japan in that order IRC.

In that order? As in Ys is a bigger seller than DQ? Really? :o

I remember Ys being the second biggest JRPG franchise in japan. I'm not sure wether it's in number of installments or sales, and I was unable to retrieve the source. I also assumed FF was bigger than DQ, both in installments and sales.
