When you play Star Wars: The Old Republic, there is a certain sort of lore speculation that holds that in 3000 years none of this will matter because we all know what happens then. (It involves midichlorians.) But there is also lore speculation about what will happen in the next patch, where the game’s current story is hinting, and when (or if) we’ll see various important NPCs again. Rather than being about making the current story line up with larger canon, it’s about guessing at the immediate situation based on the things we as players know.
Of course, many games don’t have a whole outside pile of lore to draw upon, but there’s still often enough lore to speculate about what might happen next. Players can make educated guesses about what is still to come in Final Fantasy XIV or World of Warcraft, for example. But are you one of those players? Have you ever gotten into MMO lore speculation? If so, did you lose interest in it (either due to being consistently wrong or just a lack of care on the part of the creators) or are you still involved in theorizing?
