I mentioned before, I have a clan that may try to make a move over to strat if we can figure it out.
The fundamentals are pretty basic.
Earn money by playing crpg and by working in settlements.
Recruit troops from settlements.
Spend your gold on equipment for those troops. Save some money for upkeep/costs/paying wages to people who fight in your battles.
If you have enough troops, attack a village (best done by pooling all your armies together)
A battle will appear on the c-rpg.net website, strating roughly 24 hrs from when you attacked.
Anyone can apply to fight for the battle.
Any member of your faction with a ranking of 5-10 can edit the roster.
You have to manually pay your fighters after a battle, win or lose.
If you win the battle, the fief is yours. You can change the taxes and I believe the fief owner is able to recruit a bit faster than everyone else.
Thats pretty much it apart from trading. I just wrote a small guide for that (
