The first set of drama CDs, released by NEKONEKO Software, was mostly just offshoot joke dramas for the people familiar with the game. The later ones released by MOVIC, including this one, are closer to the second OAV in feel. There're less jokes and the story is more serious. Obviously, I like these better.
Acting is much better, too. Either the actors got better over the years, sound director did a good job, or both. This set of drama CDs turned out to be great buy for me.
I can't find any flaws with the audio quality, either. Even the stereo separation is done well. I didn't intent to use more than 5 stars for non-music CDs, but this one is so impressive, I'm giving it 7 stars.
And this CD only cost me Y380!
