Planned features are : gladiatorial matches. Where you are the investor, you are not directly interfering with combat. How ever there'll be some lewd actions to alter the course. Maybe flirt with the referee to let your losing gladiator stay alive.
There'll be management of gladiators and slaves. Different events may reduce/increase their obedience and their happiness. which may lead to revolts.
Wanted to implement a randomized past system that is generated for every glad/slave. And if you try and get to know them better their stats increase. This is not set in stone probably wont happen for some time.
There'll be no significant other, i'd like people to choose that for themselves if that's what they want. as for fetishes. i'm not really a big fan of impregnation, but if the demand is high we can try that. Group sex is what defines Rome lol. There'll be prostitution, lesbian, anal, maybe some cuckoldery depending on your choices. Want to create a femdom/sub path later on.
