Erik Kain recently gave 13th Age an excellent review on Forbes.com, saying:
“…one of the best systems I’ve encountered—and I’ve either played or read the rules to countless d20 systems at this point—is 13th Age, a game cobbled together by Jonathan Tweet and Rob Heinsoo.”
He then goes on to say:
“13th Age is … fun, fast, and accessible and encourages imagination from players and GM alike. It bakes some very cool new ideas into the d20 ecosystem while keeping all the major pieces intact. Of the many systems I’ve read recently, it’s one of the best. The demo adventure I was able to play was a lot of fun, from character creation to combat, and left me excited to play more (which is a good sign.)
And since it’s part of the OGL it’s simple to use it for everything from 3rd Edition to Pathfinder. In many ways, it’s exactly the progressive design that I think a lot of D&D fans were hoping for when 4th Edition came out and that fans are now hoping for with 5th Edition.”
