It happens, but that's just a risk you'll have to take if you love cake! =O
No, no, you don't always want the exact same cake. That sounds boring! You just want more delicious cakes, more delicious Super Mario RPGs. Well, not you, but I.According to your analogy, those who enjoyed SMRPG would like to play the same game over again, in otherwords, a re-release of the game on GBA or DS or something. After all, if you really liked the chocolate cake, you'd want more of the exact same cake. They may change the recipe for the cake and you won't be pleased with the change.
Ooh, Paper Mario. <3
