Did some quick maths on how many stars you can get per month in Bandori EN just for $10 + playing semi-efficently. Came out to 6,300 stars and this isn't even including card stories, full combos, high scores, and special login bonuses. (Though my mind might totally be playing tricks on me and we don't get stars for event stories.)

But yeah, that's seriously a good amount for little IMO! Hopefully CraftEgg doesn't go cheap on us.
