I group XWN skills into three general tiers. Skill value changes depending on the game. For example, Fix is generally a very broad, useful skill in Stars, but its equivalent Craft from Worlds is less necessary. Something like Heal might seem useful, but is immediately outclassed if anyone has any magical healing, except in Stars where you need it to apply various medicines. Settings, playstyles, GM tendencies, and a host of other factors, can all make these skills change importance.
Tier 1: Profession Skills
Administer, Know, Perform, Pray, Trade, Work
These skills tend to be among the rarest used in actual play. While they are important for a character’s day-to-day life, as they usually represent some sort of job, they’re not often exciting for adventuring. Some classes might use these skills for Effort, and they might feel important for a character’s background, but they tend to be rather low value in general.
Tier 2: Concept Skills
Connect, Craft, Exert, Lead, Heal, Pilot, Sneak, Survive, Talk, Wrangle
The majority of skills live here. Depending on a lot of different things, they may move up or down a category, but in general, these are skills that entire character concepts can be based on. If a player is investing a lot in one of these skills, they should probably have some challenges that use them. Likewise, it can be extremely frustrating for a group if one of these skills is absolutely needed but no one bothered to invest in it.
Tier 3: Essential Skills
Blast, Melee, Notice, Shoot
While you don’t need every combat skill, you likely need at least a minor investment in a combat skill. While technically possible to get by with Swarm Attacks and quirky behavior, most players will want to be able to hit things. And Notice is just generally useful. It is maybe the only skill useful in every classic “pillar” of gameplay (combat, exploration, social). Which asks the question if it is too useful, and should be split up somehow. But I’m trying to keep scope creep out of this project, and rebalancing the entire XWN core is outside what I’m aiming for.
Next, I’ll try to explain Backgrounds, and why I’m not a huge fan of them as presented.
