Got Skillz?

Skills and skill systems as they relate to OD&D.

We have ported our Labyrinth Lord game to Savage Worlds and while it works well ...very well even. Its just not D&D. Years ago, for me that would have been a plus. During my rebel years when I lauded all things not D&D.

No, though I'm a reconfirmed and born again in my original faith - that of D&D and the OSR. I'm a little dismayed at the growth of our house rule document. That is however under my control and I could had line a more traditional approach.Why should I really? I think many other games have brought some meaningful technology/Systems to the original game and making use of them is I think of benifit to the flow of the game at the table.

Key to this is skill systems. I'm yet to be convinced by advantages and disadvantages (- although I think Savage Worlds and my other favorite system Hollow Earth Expeditions "Ubiquity" do a good job of including them but minimizing the addition of complexity).

So what is a good skill system? As a DM I'm happy with the OSR skill system and the way I implement it.  Lets look at it more closely.

OSR Skill system v01. There really isn't any skills and it comes down to DM fiat as to weather or not a player can succeed. The up side is the DM has complete control over moving the story forward  by providing responses to player questions. The down side is the DM has too much narrative control. In effect the DM is controlling the player character as well as the milieu and he can manipulate the outcomes far to much. More importantly the system is dependent on the skill of only the DM and I think this is both a boon and a bane.   

OSR Skill system v0.2 Under that skill system in and our old game players could attempt an attribute check on anything that was conceivably related to their class. They could make a half attribute check for nearly anything else. This is a good quick system which gets a lot done. It favors inventive players and I think they are worth rewarding. 

Rules Encyclopedia, skill system as written in those rules. The difference between this and v0.2 is a) It has a structured skill list, b) It has a number of accrued "slots" for the structured skills c) It only uses a simple roll under stat mechanic. I find this a little too structured.

I wont go to the proficiency system of revised AD&D as I don't think its much more then the Rules Encyclopedia, skill system in different clothing,  revised AD&D  was my least favorite version of D&D. Anyway there is not a lot between the two systems with "slots" being replaced by "proficiencies"  

There have been a number of notable retro clones which have added skill systems.The ones I find noteworthy (these are others I like too but these were landmarks I think in the OSR community)

Most people seem to like LotFP's d6 skill system. It does have much to be admired a) its simple and b) its just enough of a list and c) and it opens up (the Thief) skills, at a basic level to everyone, which should have always been the case.

The Majestic Wilderlands skill system which is closer to a modified  Rules Encyclopedia, skill system and the OSR Skill system v0.2 we use.

Microlight uses an elegant system of skill "clusters" sort of mega-skills which the player has and can use and are resolved with a skill check.

Castle and Crusades SIEGE engine Primes and challenge classes also gets a respectful nod.

Stars Without Number has a fully defined skill list and a resolution mechanism using 2d6. Its not  

The critical success factors as I see it for a skill system is it should;

• Be easy to understand
• Support player narrative input (as opposed to supplanting it)
• Fit with the feel and spirit of the classic rules, so it should use poly dice
• Should only be used for those activities which have a significant importance to the story OR where success/failure is important to the simulation (depending on paradigm) 
• give a pass/fail result when required 
• give a more nuanced graduated result when required

Also I think the skill system should use the Target 20 model used for combat with AC being replaced by Difficulty and the mods being environmental and other factors which increase/decrease the difficulty

TARGET 20 "SKILLS" ALGORITHM: d20 + level + Dif# + mods ≥ 20

I'm also somewhat partial to using the OD&D/Chainmail Man to Man resolution system. This would call for rolling d6's based on level and looking for "hits". 

when I can be bothered I'll pick this up again.
