This wasnt called Halloween, it was festival of the lost. Christmas season doesn't have to called as such, call it festival of light with a winter theme. Both these holiday seasons have general themes that don't have to tie to religion, but the commercialized and sensationalized version of each. I'm not against Ramadan, but What would a Ramadan holiday look like? How would it be fun? The previous two work because of iconic themes that are not tied to religion, regardless if they started as such. Other games do these types of things often.
