Sure there are many things to do...
But also there are many things which have to be discussed...
For example which direct Era we start in. before 3k? So then we would have Dong Zhuo and all that people. Much more overall action between different factions.
Or do we start when Wu/Shu/Wei are already formed?
Both has pro and cons. So that would be a thing which has to be decided, before we start doing minor things.
Before 3k its more action, but harder to do, because more overall stuff changes.
After 3k is easier to do , more static, but you have lesser options of course.
But of course we will need someone who gives the Items their Stats and creates the different troops for the factions. if you know about weapons and such things, that could be a good thing for you.
They should be more or less similar but yet have little differences.
And be named like wei footman.
