I'm still playing, but I would like the archery and roguery skills implemented. Only 2 of the archery skills work, and none of the roguery skills are implemented.
I also want the inheritance system to actually be implemented so all the children that are born are not gimp on arrival with zero attribute stats (and include NPC nobles intermarrying so that they don't all die in the next generation from not having any kids).
Long-term goals? Diplomacy and other methods to win besides only siege, repeat, siege, repeat.
some are already possible, but they suck. Prior to the retarded nerfs, when you could make a massive buck, you could raise Trading and buy fiefs from rival factions (been there, done that). Though it's too boring, and each fief would cost from 700k up to 2.5 million. In that specific playthrough I've actually bought half of Calradia lol (from my own vassals and from rivals alike) so I could organize the kingdom better, redistribute fiefs, and what-not. Never had the patience to finish it, though... The problems with the game are too annoying and discouraging. AI behaves like a swarm of bees, they are everywhere annoying the hell out of you, but never do anything logical or reasonable... They'll spam attack a "priority" target forever until they take it, even if it costs them 90% of their total troops in the process. Allied AI will ignore getting attacked, travelling ridiculous amounts of distance to besiege a insignificant, isolated, and pretty much useless castle on the other side of the map. They'll try to besiege having no food and lose 50% of the army in the process, they'll zerg rush you, the player, if you start a siege, so on so forth.
If you don't try to "manipulate" your allied vassals, for instance, it's common that you'll take a fief for your faction while losing 3 at the same time, because the armies that you are not commanding will keep having happy strolls around the map doing absolutely ****ing nothing. Then they'll snatch the fief you've captured yourself for them, to lose it 2 days later.
PS: I'm not sure if base game has that perk working, just remembered that I was using mods, specifically mods to correct broken perks.
