Kid, eh?
Now I've lost this debate for sure.
What I don't need is people putting words in my mouth.
"holy writ"??????
How about Player's Hanbook Page 70.
Under Knowledge
"With you DM's approval you can invent new area's of study."
I think Monte should have the luxury of using the rules as stated in the PH without your approval.
You get all defensive about your ability to adapt, but your entire point in this thread has been that new skills are a bad thing.
If you adapt so easily, what exactly is the problem?
"More skills make the characters stupid." -- Geoff Grabowski, designer of Exalted
Although it may be the case that in some situations, two or more skills may apply to the one question, it's likely that in many _more_ situations, DMs will feel constrained to apply only the narrower skill in preference to the broader one, if only to justify the narrower skill's existence. Thus, the addition of knowledge skills is a Bad Thing. See the ever-growing proliferation of skills in GURPS, for example.
So again the game should be constrained by a poor DM's inability to adapt?
Because if a DM did what you proposed, that would simply mean they were not a good DM. At least in this case.
I played GURPS for many years. Great game.
Note that the quote you provided is not relavent, becuase it refers to skills in general. I quite agree in that case.
A skill: tie knot would make a character with the skill use roipe suddenly stupid because it would imply they don't know how to tie a knot, and would need to spend more points to get the same ability they had before.
A version of knowledge, Know:Undead, does not in any way imply that a player with know:religion knows any less about undead than they did before.
When a third party promotes the "New Skills" they have come up with, I assume very bad things about their understanding of the game system.
There is a big difference in adding a new skill that detracts from the player's skill point allowance, and allowing flexibility in existing skills such as knowledge, craft and profession.
It seems clear to me that your problem comes from the fact that you are trapped in this, no knowledge skills may overlap box.
If you won't let go of that narrow view, then you will need to adapt material. Being as you are so proficent ay adapting material, this should be very easy for you and you should have no further complaint.
