But the passage of time and it's shitfuckery is a fundamental conceit of the narrative. Time has to pass in the game to show that there is a loop.Halloween and Christmas is good and all, especially since Selebus makes tons of progress in a year, but I kinda doubt it will be that great for new players. Many devs "cut" such updates when the time for them is past for a reason. Well, at least it can be explained with all the "time" shenanigans, but I kinda doubt its a good way to go. Maybe its better to make such updates once every 2 years so there is more time to prepare and have less loose ends.
As opposed to the characters saying "it has now been 3 months since the start of the year" major cultural events are a pretty slick way of showing time pass.
Plus my enjoyment of media does not require the time of year in said media to be the same as my time. There is no reason to refuse to acknowledge the existence of Halloween and Christmas for the other 10 months of the year.
