I adore holidays! IRL, Christmas is my favorite. I'm not religious, I celebrate it as a celebration of winter, which is my favorite season. So naturally I celebrate it in the game, as well! I love decorating so much IRL and in game! I was so happy when I was able to learn how to do custom content, because then I started being able to do more.
The only problem I have with The Sims 4's take on holidays is that it comes in a checklist format. The Sims 3 is much more limited as in you only have the four holidays, but they fit more naturally into the gameplay, whereas The Sims 4 you have to initiate so much. I want holidays to fit more seamlessly into the game.
I also miss being able to create lots that change with seasons. I await the day when that can happen much more seamlessly as opposed to freezing my The Sims 3 game when the change applies.
In TS4 I have quite a few holidays, most of them are based off of real holidays. I try not to pack the calendar too much because it can turn into more of a chore than a fun variation on some days. Sometimes I struggle to get everything in without it feeling cramped since I play with the shorter 7 day seasons.
