I'd like to see topics that may not be covered all that well. Such as guilds of all types. I liked the concept of organizations and rules around those, but expand this further.
Owning a business (taverns, magic shops, etc), building and maintaining larger properties, such as keeps and castles.
Mass scale combat for larger all out wars. Vehicle combat, such as chariots, and "other" types.
Lets see some new things not just rehashes of material already out there.
