Now that I have a bit more time to think of some more points for here.
Combat Rules
I strongly support using a more narrative or faster approach to grogs fights or lower stakes combat. A friend told me about one PbP he played in where there was no dice-rolling, and people simply reasoned out the expected outcomes of an encounter given the circumstances. I heard it worked really well, with there only being a handful of times where people disagreed and had to hash things out. I think that kind of approach could work well for really simple things. Eg "The heavily armed and highly skilled martial companion makes short work of the opposing group of conscripted guards, taking a light wound unless they get some magical assistance".
Absences
We should alert others if we have an extended period of things happening or an expected amount of absence. I would think that whatever acting Story Guide could control the characters of absent players, although that's an important point to agree on.
For disappearances, I like waiting for whatever one posting period is and then having the SG take over a character.
Text-Formatting
I have no strong preferences for any specific kind of formatting, but I think we all need to agree to do the same thing.
Dice-Rolling
I don't have a preference here.
Creation of a Wiki
How much information and research do we want to include for the saga? Having a dedicated wiki to keep track of large amounts of people, places, events, and so forth could be beneficial. That said, I am in favor on sticking with the forum here and its wiki feature until we deem a time when it's necessary to do something else.
Story Frequency and Duration
I already mentioned one idea I have for a long spanning game. I personally sometimes like to really pack adventures into important years or around big events. I think in my current running saga, we put like 6 adventures into one year where the Albigensian Crusade really flared. That's not something we would need to do every year or all the time, but I like the option of really making events fly every so often.
Confidence
I like the idea of letting characters restore confidence at the end of a year.
House Rules
Can we get rid of the Swim Ability and just fold it into Athletics? It seems unnecessarily siloed off to me.
I like switching the Tremere house virtue to Puissant Certamen.
I think this is unnecessary. The bonus from having good stamina is nice, but it gets dwarfed pretty quickly by everything else involved in spellcasting. It's not that much of a penalty to have a worse stamina than another character, especially considering all the other areas you can gain or lose on your spellcasting totals.
