I got done with the Mass Effect trilogy recently, and decided to put my thoughts on paper, but when it came to writing about the plot and world design, I've ended up with so much typed out that I don't think any reasonable person would want to read what amounts to a massive summary of the massive plot. I was also planning on writing about gameplay, but then, this is such a broad category that I worry I'll get caught up in minutia and end up with a similarly massive section. Music and Visuals are topics I wish to address as well, but I don't know if these are critical, or if I'm ignoring some other key elements of games.
