I think i'll create holidays following the theme of the sims. An example of this would be creating Leisure Day from a past seasons expansion. I also think it would be cute to create Grandparent's Day. I saw that in an earlier post on this thread after I thought of it! I want my holidays to have the names similar to Maxis created ones ex: Winterfest, Love Day instead of Christmas or Valentine's Day. I like having somewhat of a difference between real life holidays and fictitious ones for gameplay. I'll probably create (if not already in the game) Spooky Day, Snowflake Day, and so on.
