We had high hopes for 13th Age, but its popularity took even us by surprise. Very quickly the game attracted a strong community of passionate fans who’ve run some amazing campaigns, and used the new DIY-friendly mechanics created by designers Jonathan Tweet (D&D 3rd edition) and Rob Heinsoo (D&D 4th edition) to create new classes, spells, monsters and magic items.
Check out the latest testimonials from Twitter and Google+:
“You know 13th Age is a unique creation when, depending on who you ask, people will insist that it’s a direct successor of D&D 3.x, or of D&D 4E, or of the OSR. I think it’s a combination of all of the above, and people are focusing on certain aspects of the game when they make those comparisons. We’re getting the best of all worlds with 13th Age.” - Tim Baker
“I really enjoy 13th Age — the game rules, the setting, and the lovely bullshittery it enables. All kinds of fun.” – Patrick Weekes
“Our 13th Age campaign is blossoming into one of the most amazing, highly improvised RPG campaigns I’ve ever played. So much so that I consider it one of the high points of my GMing career.” - Philippe-Antoine Menard, the Chatty DM
“It makes clerics fun, and makes a mechanic of setting fluff. 13th Age rocks.” - @FrayJoker
“While reading through it, I think I finally hit upon why I like this game despite its D&D 4e roots: many rules are expressly stated as some variation of ‘use common sense’ or ‘do what makes sense for the fiction/situation’. I like that a lot. I’ve moved away from rules-heavy games (both as a player and as a GM) specifically because I often feel constrained by the system in ‘crunchy’ games. I don’t need rules for coup de grace attacks and other actions that should have very concrete fictional results. I like systems that get out of the way by themselves, without me having to intentionally ignore rules.” - Christopher Stone-Bush, Idle Red Hands podcast
“My players (and I) loved some parts of 4e, and it has taken those parts, along with the best of AD&D, 3.5, etc, and made the best d20 game I have ever run/played.” – David Thomas
