The audio production, acting, and damn well everything is top notch. Jeff Hays is incredibly talented.
The only downside to this series and it’s narration is that it will ruin you for most other LitRPGs.
Yes, it’s THAT good.
I have the entire series in audio, and am halfway through Book 2.
Read all the books when they came out, bought the series audio once I had enough credits to binge 1-5.
