Ok so it's a tiny bit tongue in cheek but in all seriousness I do consider Blue Stinger to be an actual Christmas game in the same way I consider Die Hard to be a Christmas movie...which is to say 100% it's a Christmas game

Points in its favor : Christmas setting, Christmas Decorations, Christmas music, DOGS Bower (kind of looks like Santa)...and I was gifted it for Christmas back in 1999. Which is crazy to think that was 21 years ago now
Points not in it's favor : there was not a single family argument in the entire game so that took away from the holiday feels

But joking aside there are few games I associate with Christmas as much as I do Blue Stinger. Such a weird and charming game...it's "Christmas Holiday Survival Horror"....making it the Die Hard of Christmas games
