This piece started out to be a retrospective on Morrowind. But somewhere between the sketch of the ideas and the completed work, it morphed into something a bit different. Yes, it is still mostly about Morrowind. But it also focuses on how mods, in general, have added so much to many of the best games any of us have ever played. Indeed, during the writing a profound conclusion solidified for me — many of the best games became "best" because of their support for mods.
