TSM had so many cool things, and since it ran on the same engine as TS3, part of me wonders how hard it would be to give us some Medieval conversions into PC content. Things such as:
Mining Rocks: Even if animations aren't transferable, we already received a mining animation with WA. You can mine these rocks to get metals and gems.
Gambling Table: Could play card or dice games. Would also allow sims to make bets with other sims (One sim will win after 12 hours to 3 days). The higher your gambling skill the more likely you win the bet. It would also enable pick pocketing, which can help your sims make lots of money.
Combat Arena: Your sims can wrestle and engage in sword fights. Or if they feel up to it, they can take the swords and press other sims for money. It would be cool if this also enabled the 'Spit in face' interaction.
Writing Station: Sims can write novels without using a computer. They can also write poems (Which they can recite whenever, dialogue copied from Medieval), or write plays/musicals (Dialogue and song (If musical) copied from Medieval). Finally sims in the political career can write treaties, which improve job performance, or write new laws.
Writing laws has a success rate dependent on your Charisma Skill, Logic Skill, and Politics level. So if a sim is not in politics at all, but is very charismatic, they can still get laws passed.
Laws can be used to set curfew times (Or eliminate them entirely), legalize things that will currently get you busted by cops (Graffiti and Theft), or make possession of objects illegal.
The Pulpit: This is probably the most controversial but may be easier done than the writing station. It essentially adds in religions (Which are referred to as Ideologies). Your sim can click on the pulpit to create an ideology, which comes in the form of this GUI:
Ideology Name:
Leader:
Follower:
Followers:
Symbol(s):
Qualities:
Meeting Place:
Meeting Time:
The first 3 are just what names the game will use. So if you wanted to do an Ideology based on Catholicism, you would put this into the GUI:
Ideology Name: Catholicism
Leader: Pope
Follower: Catholic
Followers: Catholics
The next would be optional. These would be the symbols seen in conversation when people talk about your ideology. So if you wanted an environmentalist group, you could pick out the color green, and then symbols of the earth and of trees.
Qualities would be what your followers ideally do, such as traits, skills, and interactions. If your ideology is a brainiac group, traits could be 'genius', skills could be 'logic', and interactions could be reading.
The final one is meeting time and place. The leader can schedule meetings at their house, but they can also schedule meetings on public lots.
The Pulpit would unlock several new interactions:
-Debate with other Sims
-Convert others to ideology
-Speak from the pulpit (Helps increase donations to the ideology when done at meetings)
-Evangelize (Like converting others but less effective however more people listen)
That is the secular part, and it could be used completely separate from any religious notions. You could use it for gardening clubs.
If very unspecific religious actions were added, these would be my ideas:
-Praying, and praying with others (TSM animations)
-Blessing Sims (Gives them a positive moodlet)
-Blessing objects, which turns them into icons
-Praying over icons.

Actually, I found out at least for the Peterans the Insightful tone is the best. It ALWAYS raises the meter, and at that faster than any other tone.
The catch is that unless your priest is level 10 (which is a lot easier these days), you have to study the watcher before giving the sermon. The insight buff has to be still active when you give the sermon.
Basically humour or gloom are good and fine, but just like IRL, those people like it more if it sounds like you did your homework and can tell them some insightful-sounding stuff. They're not coming to the church just to hear jokes.
Basically my Peteran monk's day starts with him getting outta bed at 5:30, eat, study the watcher, and by the time I'm finished, maybe I have time to use the chamberpot or convert someone before giving the insightful sermon at 8:00. Works like a charm every time.
Dunno about the Jacobans, I never liked them enough to play them.
Of course, I don't have to say, the focus bar being high also helps. If you did the Meat Quest IV quest first for example and picked the right choice, a Master quality meal gives a hefty focus boost, for example. All the more reason to have the sermon at 8:00 before the effect wears off. And the insight buff from studying the maker also helps, on top of allowing Insightful sermons. If you're scholarly, you can also try to find the time to read a short book right before the sermon, or really, make the most out of whatever traits you have. And at that point you should be pretty buffed up.
If you want to raise that bar even faster, go evangelize afterwards, as the buffs are still up. Doing that every day and converting lots of people should help rake in some profits.
Of course, it still won't stop people from swordfighting and playing the fiddle in church, but, oh well..
