in its current form yes I agree but all they need to do is add new games to give more options of winning and the high price wont seem as bad then.

my 2 cents

1. add a battle arena like 7 where you fight with different handicaps. each wave survived you get MGP and the ultimate prize could be something rare or high MGP

2. Add slots from FF13-2....god dam I love me a good slot machine game and that would drastically give people a better chance of earning MGP
