That is true...
I regard knowing all of the important details about the main plot as an achievement that I have yet to achieve. I am really not sure that playing the games would make it any easier to take in the story, because even with the two games that I have completed there are still parts that I am confused about. I know that re-watching the cut-scenes would be the easiest solution, but even then, there always seems to be a lot that is open to confusion. When I watched the cut-scenes for Days, I do not remember seeing anything that helped answer my questions specifically. Specification is one of my main issues. Unless something is clearly stated by some source, understanding the series can be difficult.
I know that I can be demanding, as Professor Ven said, but I try not to be, and this is why I do not feel comfortable about making threads that are purely about questions. I prefer receiving straight answers, which never seemed to be a problem before, so I am confused about why it is such an issue now.
