Overview
Anytime I find a thread online where someone is asking for recommendations of games to try, 13th Age gets mentioned. It's a few years old now, being published in 2013 and was written by big-shots in the game-design industry. Here was a game created by people who designed two editions of D&D, and then went away and used their experience to make their own fantasy rpg, now free from loyalty to the D&D brand.
I had heard this game included a number of clever innovations, which later writers included. The Advantage mechanic, which is touted as one of the great features of D&D5e, was actually first seen here. I had heard it had combat which was just *fun* and encouraged teamwork.
