Hiya, I'm interested in both of your ideas, however the second seems a bit more "coherent" ... shall we say? For the first one (are you referring to Romance of The Three Kingdoms saga?) I can play as either one of the princes, or the princess herself. Won't you need more than one person for this or would you be willing to play multiple chars?
For the second scenario I'm once again open to whoever you want me to play. Brother or the sister. Take a look at my ons & offs, and if you're interested let me know.
