Currently, the Storytelling and Storyteller Systems have primary/secondary/tertiary skills/abilities, and at character creation, the primary have more points, whereas the tertiary have less points.
For example, in the New World of Darkness, the following points are given at creation
| Attributes | Skills
------------+------------+---------
primary | 5 | 11
secondary | 4 | 7
tertiary | 3 | 4
------------+------------+---------
But once the character starts to play (i.e. winning XP), the difference between primary/secondary/tertiary traits are lost.
One of the consequences (undesired for us, ST in our group, for multiple reasons), is that characters are not specialized enough. We want to tweak the system to have the characters keep the physical/mental/social "specialization" they applied at creation.
The solution is the following: Change the XP cost of those traits.
| Attributes | Old Cost | New cost
------------+------------+----------+----------
| primary | 5 | 4
Attributes | secondary | 5 | 5
| tertiary | 5 | 6
------------+------------+----------+----------
| primary | 3 | 2
Skills | secondary | 3 | 3
| tertiary | 3 | 4
------------+------------+----------+----------
We believe the system is good to produce the results we want, but I wanted to have feedback about the pros and the cons (we could have missed) of this tweak.
What's your viewpoint on the tweaked system?
