For one of the "old type" games that I described here, getting a day of scenario tickets (five tickets) is 450 platinum. There are 11 chapters, and I think each chapter of the story takes 15 tickets. So if you wanted to purchase one chapter it would be 1,350 platinum, which is over $13. I think it would probably be over $150 to purchase everything.

I hope those numbers are all correct... And let me know if you need any more help. :)
