Worldbuilding 101: The 10 Scale
When creating systemless settings, a basic benchmark can be used to allow for conversion to the system of choice. For simplicity, every descriptive item that should be measured can be rated on a scale of 1 to 10, with 1 being the lowest, 10 the highest, and 5 average. When applying this to other systems this will be relative, as not all systems are linear or even consistently exponential. The gamemaster should exercise their best judgment to determine what is most appropriate for the system of their choice.
Rating the Overall Character
This applies to character classes, templates, and archetypes and is handy for writing thumbnail supporting characters. Any general description can be written down and given a numerical rating: Wizard/7, Salesman/3, Starship Engineer/9, Detective/8, and so on. If you list the character as Fighter/3, then they do fighter stuff at 3. Context within the setting itself is important. The meaning and capabilities of Thief/5 will be different in a medieval fantasy setting, a modern espionage setting, and a futuristic space operate setting.
Rating Individual Abilities
If a character has a breakout ability, something rated higher or lower than the overall character rating or not included within the class/archetype/template structure, it should be called out. Machine gun/6, for instance, would not be intuitively included for an Architect/7 character. “Negative abilities”, such as disadvantages, can also be noted in this manner, with the strength of the disadvantage noted on the 10 scale. Not every individual ability needs to be noted, just those that are unusual or outstanding.
Abstract Abilities
Not all abilities will require a rating, or may be descriptive in nature and difficult to rate. These should be noted, even if no numeric value is assigned.
Task Difficulty
Tasks are also rated on a scale from 1 to 10, with 1 being the simplest, 10 the most difficult, and 5 being average. An average character (Rating/5) should be able to accomplish an average task (Difficulty/5) most of the time.
Damage
A weapon’s damage rating means there’s a good chance that weapon could kill a character of the same rating. That doesn’t mean it will, just that it can. Weapon/7 can kill Character/7.
Conversion
Using the 10 scale makes conversion of descriptive characters, abilities, and gear into other systems relatively easy. The gamemaster should make the determination as to what the equivalents are in terms of the system of their choice. Below are some suggestions on how to convert 10 Scale descriptions into a few popular systems. These should be used, tweaked, or ignored as best suits your particular tastes.

World of Darkness
Rating equates to the total number of dots in Attributes + Trait. Special abilities are rates separately, so all together it is possible to have an overall rating higher than 10 when ability dots are added together.
Savage Worlds
Rating / Die / Rank
1-2 / d4 / Novice
3-4 / d6 / Seasoned
5-6 / d8 / Veteran
7-8 / d10 / Heroic
9-10 / d12 / Legendary
Percentile Systems
Multiple rating by 10. For example, 6 becomes 60. To convert the other way, divide by 10 and round. 52 becomes 5, 77 becomes 8.







The other day my wife the non-geek asked me about Ed Wood. Actually, she asked me to explain Ed Wood (the actual person, not the movie) to her non-geek mother. Because I will latch onto anything that might bring the wife a little bit further into my geek world, I obliged. The summary I gave was that he was a man whose passion and vision for film far, far outstripped his actual budget or talent.


Way back in the year 2000, John Wick wrote a fascinating game called Orkworld. It spun out of a bet that was in turn inspired by his wanting to run an orc bard in D&D and being told orcs don’t have bards. Being John Wick, he went off and created an intricately detailed culture where orks (with a ‘k’) have a rich and interesting culture and can, among other things, be bards.
