I had originally wrote a 5-star review after initially reading the full rules but playing the Jumpstart Kit. The game is easy to learn, create a character, and adjudicating the rules. You can pick up this book, quickly create a crew of edgerunners and start playing. It is simple while offering a fair amount of crunch.
I apologize for that.
I've since deleted that review after running a six month campaign of the full RED rules. In short; this game stinks. The book is a layout artist's nightmare, and even with bookmarks it's hard to navigate. This is because of redundant sections of rules. If page count is money, this book wasted a lot of money. Many of the rules don't make sense, like armor-piercing, cover, supressive fire, and melee combat, etc.. Skill costs are out of whack. Some Role Abilities are very OP while others are lackluster. While NETrunning was streamlined, it's still a mini-game and doesn't work as they probably intended it to. Don't ask me about vehicles. The setting doesn't know what it wants to be. It claims to be cyberpunk, but the author obviously wanted to make a post-apocalypse game instead. Cyberpunk used to be about "style over substance", but that's completely abscent from this edition. If you came to this game to play a ttrpg version of Cyberpunk 2077, forget about it. You're going to be very disappointed.
My advice: Cyberpunk 2020 is still a good game. It needs some houseruling, but it's a much better game than this slipshod.
