Carrying this over from the Rigger Dossier thread, in case things get moved about - inspite of the Rigger Dossier being the reason more people found out about how Knowledge Skills work in 6e.Have you EVER been in a position in 5e (or any other edition) where one of the PCs had a knowledge skill that replicates the knowledge level of a world class scientist?
6e will.
Because either you don't have the Knowledge Skill, or you replicate the knowledge of a world class scientist. Just because there is no other level available. (At least that you are capable of talking about.)
Anything else, and you are trying to compare oranges to crayfish.
To use 5e, if a rank 1 in a Knowledge Skill indicated Masters Degree - I could say whole heartedily that I routinely met that criteria. Why rank 1? Because it is the binary opposite of rank 0, the same as having the Knowledge Skill in 6e.
NPCs just sometimes don't conform to rules that govern PCs.
And that is the single most myopic failure of all role playing game systems. If you believe otherwise, you haven't been paying attention for the last 25 years.
You have prospective players (some on these forums even) complaining that armor not preventing damage and impossible shots - at worst - impose a -2 Edge penalty (give 2 Edge to the target) defy all believeability and you somehow think that PCs living in a completely different environment from the
rest of the game world is going to go over well?
Seriously?
What players want, more than just about anything else (assuming the system in question matches the story in their minds) is a game system that is consistent across
all aspects of the game world.
If a player decides to make an Doctor of Archeology that Decks to make ends meet, and takes 3 different Archeology Knowledge Skills to represent his/her PhDs in those fields... They
do not want to find out in game that the Knowledge Skills only represent the freshman course and that PhDs are only really handed out by the GM when the mood suits them.
That isn't to say that PhDs have to be handed out to anyone who takes a Knowledge Skill. It might suffice to have a Positive Quality titled Masters of [Knowledge Skill] that represents that. It can be so insanely expensive that no character would, even if they could, buy it a chargen. It could even have "GM Approval Only" as a requirement. All of that would likely suffice, because at least the player
has a path towards what they want for their character.
Or, put another way, players really, really,
really, want PC physics to match the rest of the game world physics.
When they don't, dissonense occurs.
