Solid information for Game Designers
Format: Paperback, Format: Paperback
Level Up was a great read. It flows well, hits all the important stuff, and it's fun to read explanations from games I've played growing up.
I went to school for Game Art, and Level Up covers everything they taught minus the hands-on experience that the classroom has. Cover to cover of great information.

Typos make this appear sloppy and questionable
Format: Paperback
Number of typos in the first chapter alone makes the info contained within questionable to me. P. 11 Indie games are “mostly releases through streaming services like Twitch and Switch”. Twitch is a streaming video site and Switch is Nintendo’s hybrid handheld/console.
P.13: SHMUP is misspelled as SHUMP
Survival Horror is listed as “players are generally helpless against a supernatural threat” which is not accurate for the genre’s most popular game, Resident Evil, where you’re well-armed against a non-supernatural threat.
Vehicles simulation is listed as a genre but racing is not…even though they are not necessarily the same genre.
P.14 Shigeru Miyamoto’s name is spelled as “Shiguru” I’m sure the following chapters will cover Ye Suzaku and Jean Romato.

Level Up Again: Essential Third Edition for Video Game Designers
Format: Paperback
If you’re serious about making fun and successful videogames, you will buy, read and learn from Level Up! 3rd Edition. I was the first person to pre order the 1st edition, and as someone who worked alongside Scott Rogers at videogame publisher THQ, I can tell you this newly expanded volume is the most complete, accessible guide to video game design yet.
Scott Rogers remains the “heavy hitter” I described in my original review—equal parts lifelong gamer, pen and paper enthusiast, and seasoned industry pro. He’s witnessed games evolve from the ground up, studied every mechanic, and distilled decades of professional game design wisdom into lessons both beginners and veterans can apply immediately.
Building on the solid foundation of the 1st edition—history, team roles, idea to concept mapping, the Triangle of Weirdness, and the Beat Chart—the 3rd Edition has been expanded to cover today’s challenges. You’ll see how to develop ideas with real world appeal and weave monetization strategies into your game designs from day one.
A new chapter on playtesting walks you through structuring tests, gathering actionable feedback, and iterating mechanics, saving you weeks of blind alleys.
There’s an in depth exploration of pre production through post mortem so you can avoid feature creep, scope collapse, and production bottlenecks.
You’ll also find dedicated guidance for console, mobile, VR/AR/MR, and live service games—including detailed control schemes, UI/UX patterns, and economy rules tailored to each platform. And consistent with the first two editions, Scott includes new exercises and analogies—even an original chili recipe that illustrates balancing risk versus reward in game economies (and because Scott loves chili).
You’ll still find the clear “Universal Truths” synopses at each chapter’s end, an updated table of contents and index for quick reference, and the cartoons and Rogers isms that make complex concepts easier to understand. If you want to level up your game design knowledge, grab this 3rd Edition of Level Up! For a deep dive on the original material, see my full review of the 1st edition on Amazon.
