What players say

At the table

The notes hold nine firsthand reports across four threads, and most are positive. Tables describe a D&D-style game with more crunch than most OSR games. It runs smoothly once learned and holds up in long sandbox campaigns. Character creation is the most common complaint.

What works

Long campaigns hold up. One GM ran 50+ sessions of Greyhawk, and others say advancement and endgame content keep a long game interesting. (thread)
Old-school adventures run as written, usually with only shock damage added. (thread)
Complexity stays steady at higher levels without analysis paralysis, and no single build was clearly best. (thread)
Running it is fast. Combat doesn't bog down, NPC stat blocks are easy to improvise, and D&D players pick up the structures quickly. (thread)
The skill system and GM tools (world generation, tables) get praise, and the tools work with other fantasy games too. (thread)

What tables struggle with

Character creation sends you all over the book. One GM wrote a handbook to cope. (thread)
Another GM called creation a chore with limited options, and said the book's layout doesn't help. (thread)
Some wanted a better editor. The Vancian spell names are a hurdle (easy to replace), and the default setting bored some GMs. (thread)
It takes more work to master than Whitehack, for both GM and players, and may suit casual players less. (thread)
Tables disagree on feel. One found play tedious and lethal, while shock damage makes melee deadly for non-warriors at others. (thread)

Who it suits

Groups that want a long, frequent sandbox campaign with a bit more crunch than other OSR games.
GMs who can put up with a rough creation process, or write a handbook to smooth it.
Less suited to casual players or anyone who dislikes front-loaded character building.

In players' words

"WWN feels more like a super solid D&D chassis with just the right amount of crunch and customization." (thread)
"Character creation can take you all over the book in a really rough way." (thread)
"my favorite aspect of these games is running them, which is to say they are a breeze." (thread)

8.1

DCC vs Shadowdark vs WWN vs OSR in general

The thread compares several games, but five commenters describe running WWN themselves. Their reports are mostly positive: a 50+ session campaign, a long-campaign favorite, and easy adaptation of B/X material, with complaints about character creation and book layout. 5 firsthand · 28 comments

6.0

Shadow of the Weird Wizard vs. Worlds Without Number

The thread compares WWN with Shadow of the Weird Wizard, and most comments are opinions or about the sibling game SWN, so very little of it is real WWN play. The two people who did run it disagree: one found it kept a steady level of complexity without analysis paralysis, and the other found character creation tedious, options limited and play lethal. 2 firsthand · 33 comments

7.5

WWN or Whitehack?

The thread is mostly a WWN vs Whitehack choice by someone who hasn't played either, and only one commenter describes extensive play of WWN. That commenter finds it a solid, D&D-like system with a great skill system and GM tools, but harder for players and GMs to master than Whitehack. 1 firsthand · 19 comments

8.0

Worlds Without Number vs 5e 2024

The thread is mostly advice on picking WWN over 5e for a science-fantasy campaign. Only one commenter describes actually running these games, and they say play is fast and smooth with little to learn for D&D players. Other comments are recommendations or hypotheticals, not accounts of play. 1 firsthand · 8 comments
