My difficulty is 102%. Everything maxed and battle size at 75 (not enough RAM to max it for more than several battles and this motherboard won't take any more).
BTW - I'm at day 93 and I already taken and defended Barriye. 1100-ish Sarranids showed up, and it took me several reloads until I found a way to beat them. They had two other wars, FFS! They shouldn't be able to mount such an offensive! Whatever - more renown for me.
As far as tweaks go, I tweaked bows to shoot a bit flatter, Coursers to have more maneuverability, Cattle follows you and I increased bandit party sizes by 100%.
As far as Cheats go, I healed my horse a bit (several times in total) when I was low level and I was soloing those big bandit parties. I never healed myself, though. What's more important, I often use Ctr-T to see the map. This one sped me up the most, I guess.
I'm not sure what I think about this cheat. Racing is already depending on luck a lot, so I argue with myself, that if I use it then part of the luck dependency is gone, but if you call me a cheater, I'll accept.
Edit: I forgot that I modded Right To Rule, so I don't have to worry about it, and I modded Prsoner Management too, so one point in it is enough. I might try another run without those tweaks if this one goes OK, although without bigger bandit parties.
