Some games enjoy a lively audience and a dedicated development team and so evolve over a period of years. Arqade has been around long enough to have questions that were asked at a time when a particular capability either didn't exist in a game and now does or was accomplished in a different way today than it had been in the past.
Generally, I believe an answer should keep the context of the question in mind. If a question was asked five years ago, and someone chooses to answer that question today, the answer's author should consider that the context of the question is for a version of the game that existed then.
A good example is Minecraft. Many of the admin capabilities that are available today weren't available five years ago. I believe that answering a question that was asked five years ago by saying, "Today, you can do it like this", isn't useful in the context of the question if the game evolved significantly in that time.
Am I wrong about this? Should I be looking at this in a different way?
