I've tried strive for power long time ago, can't remember exactly how it was and don't know how it's changed nowadays; a few things I remember: it wasn't bad and had a good art, much more focused on management than BK, the exploration feature is risky if player takes it too easy. Imho Brothel King offers a good challenge for management without too many details to take account, a lot of events during city exploration, many side quests which involve NPCs, so it's generally less static than SfP.
Is Free Cities this one:

Lilith's Throne is a text based rpg, don't know if tere are any H pics at all there, anyway its genre is different from BK.
Brothel King is a management game with rpg and visual novel features, its greatest feature is everyone can make a girl pack and include it in the game without worries of compatibility with older saves or versions; brothel and slave managements don't require a graduation in Economics; city exploration allows to meet a lot of NPCs, many of them having their personal side quests and events; there's a main storyline (actually at fisrt chapter) that the protagonist will follow, making choices which will change the outcomes of many things and the relationships between MC and NPCs.
Shortly, BK is a dynamic game with easy game mechanics and personal choices, so every player can choose their own game style without being forced to learn complicated things in order to succeed. As long as you don't go bankrupt, you can play any way you like.
