You juggle 4 resources in this game, just as the main UI lets you know.
They are: Capital, Knowledge, Political Power and Army Prowess.

Your capital, your money at hand, is the most vital resource of them all. Without it you'd have no kingdom.
Hiring professionals, erecting buildings and keeping your personnel happy will all eat away at your coffers.

Knowledge, instead, is vital for accomplishing your goals.
To beat this game, you need to progress through a tech tree and complete an Immortality Potion right at the end of it.
Until then, your smarts will still serve you well in strengthening your kingdom.

Your Political Power will make it easier to influence others.
Using it, for example, to convoke others for an audience will let you hire individuals you wouldn't see usually.

Your Military Prowess will let you deflect attacks from hostile lands and quell rebellions before they threaten you.
Rebellions tend to be harder to deal with, so to start just think of it as your kingdom's ab

As per royal decree, all of the retainers in your chambers can and will sleep with you.
Letting them get involved in the handling of your kingdom will increase your resources.

Knights will better your army, scholars your technology, merchants your political power and maids your social reach.
Your kingdom's income will be affected by these parameters.
But if you have a scholar with military strength, for example, they won't add to your army.

Improving your relationship with your subordinates will also let you impregnate them, or get into a casual relationship.
The retainer who has your next in line will of course be a mother to that next generation!

All retainers are randomly generated, and this includes not only their looks, but their stats, ages, affinities and personalities.
Gather the retainers that fancy you best, and enjoy your royal harem!

Succession is vital to your kingdom.
If you don't have a successor ready when the time comes, you'll get a game over.

And of course, to guarantee your lineage you need to creampie the hot, huge-titted retainers who follow you!
They'll all happily birth the next king in line!
Anyways, just have lots of sex!

Only your direct descendants will be able to make a claim for the throne.

Once they're born, you'll be able to check their stats to decide whether they're fit to rule or not.
Their stats will be decided by the abilities of the previous king and mother.
If you lay your hands on strong retainers, they'll birth strong kings for you.

You'll only be able to proclaim 3 of your sons as heirs, but by developing [Heraldry] in the tech tree, the number will go up to 5.
Of course, those not proclaimed as heirs cannot make a claim to the throne.

Erotic scenes include a touching system.
Your basic touching areas are the mouth, armpits, breasts, nipples, stomach, crotch, and thighs.
You can ejaculate over any area you want, and talk with retainers while they're covered with your white sticky stuff!
Their reactions to your touching will vary depending on their traits and affection.

Even if your queen hates you, she'll still sleep with you and birth your next in line!
And if your queen's head-over-heels for you, steamy sex awaits you!
If you need your wife to be your mommy, that also goes!
Or get intimate with women you don't plan to marry!
Enjoy all this freedom at your disposal!
