Just a few hints for those who find things difficult at the start. First remember that you are immortal, but your harem is not (at least at the start--may change later but I'm not there yet). You don't need to fuck a girl right away, trying to recruit too early will slow you down.
1. Work in shop until you have enough money to buy the bed (5 actions per month).
2. Alternate work and club to build charisma until you can teach at theatre. Alternate teaching and learning at theatre until your charisma hits 100 and you're pulling in $100+ per acting lesson taught. You also should have slept with the three prostitutes to raise your sex skills.
3. Buy watch and suit. Stock up on cheap gifts, coffee and wine.
4. Go to hospital and raise sperm production. Start pulling girls and impregnate them.
5. Remember that the key to raising affection is dating, romance, and gifts.
6. Balance your economy (money, sperm, spirit). Start conducting dark rituals. By the time you conduct 16 you will have the ability to charm and raise fertility on all your harem.
7. Court, fuck, impregnate to max spirit generation. Start grooming children as they grow and mature. Keep a cash reserve of 400 to 600 minimum as girl children require 200 child support on birth.
At this point you should have a harem of more than a dozen girls with 20 or more children, 8 actions daily plus at least 2-4 actions from meditation conversion of spirit, enough sperm (with Viagra) to impregnate 2 girls per month (after raising their fertility and your potency). You're now entering the mid-game and are ready to move on to taking control of the city and more advanced spells and abilities.
