Character Creation
My approach to character creation in L5R is usually to invest quite a bit in Rings from the initial XP. That will give you a better dice pool, and a better Insight, especially for those who aren't of the Courtier class. Those can derive reasonable benefit from Courtier and Etiquette 3.
Ancestors are nice, but not necessary.
Advantages and Disadvantages can be helpful in highlighting certain aspects of your character.
If you're familiar with the setting, and the rules, try and look forward, to what paths or Advanced School you might want to pursue, so you can start preparing for that. You don't have to, but if something catches your fancy, it's nice to be prepared.
Whether you're familiar with the setting or not, always feel free to ask me questions.
