I beat the game a few days ago and upon trying to get all of the Riddler stuff I found Calendar Man in the jail cell of Two-Face's court room. I thought it was a neat little easter egg to put in this game. I noticed when you talk to him that he keeps mentioning Halloween and to visit him then. I looked at the trophy list and one of the acheivements is called Storyteller and its description is "Have 12 Murderous Dates with Calendar Man". So aparrently there are 12 different holidays you have to visit him in order to get this trophy. I'm excited to see what happens on Halloween, but I wonder if this means if you miss one holiday that you have to wait a WHOLE year to get it again. I really don't want to pull an Animal Crossing Resetti and cheat to get each holiday, but I don't know if I have it in me to remember to boot the game up each time one comes along!
So has anyone heard if you can cheat the system and get all of the holidays by changing your systems date? If not I'm gonna have to mark in on my real calendar or phone or something to remember!
