I wish he would build upon game mechanics along side adding extra characters. There is so much potential for additional laws, paperwork, irregularities and even whole new extra game mode with randomized laws, posts and objectives each week (like get x pairs of underwear while maintaining throughput of x people a day with maximum of x mistakes a day).
I guess he has no plans for it, and since there is no real way to mod the game to this extent all we can do is to wait for
Mandalore777 and his upcoming project.
