Short answer is this book is highly recommended and i love it to bits.
When i saw that this had come out i was intrigued because the shadowrun mechanics is overwhelming in the core system. Now that i had my first run i feel like i can focus on what is really good about shadowrun, The world and ignore all the fiddly bits. I recommend this to ANYONE who feels that the mechanics of shadowrun is too daunting and frankly time consuming. I do enjoy shadowrun 5 too but this makes it sooo much easier.
