If I had it to do again, I'd use the same rules I wrote, take out some of the 'movement' phase stuff, and make the following changes to the plot.
- No story. I know, counter intuitive, but it's hard to do when getting started.
- Make people have 5 people before being able to start their own kingdom.
- Characters who have no kingdom (by choice, or because they can't find one that will accept them) either team up with defenders, or are mercenaries hired by kingdoms.
- Once a month have a battle day.
2 years ago, I'd make these changes and try to start the LARP up as a better version of itself. I just don't have it in me anymore.
