"Slaves of Rome is an adult RPG training simulation game with a strong emphasis on
consensual BDSM."
I must have missed something - what part of being a slave in ancient roman times was "consensual"? Someone's really trying to cover their ass! But hey, they put the LGBTQXYZ approval tag in there, so maybe the social justice pansies that run Patreon+Paypal will overlooks this one, seeing as how it's so "consensual and inclusive"!
Having said that, this looks great, if it pans out. However, given the high fidelity level they're going for (with Unreal engine and all) I doubt it will ever reach a finished state. Hell, look at how many Ren'Py "creators" abandon/restart their games - and there's FAR less of a workload using that engine than a full fledged 3D one. In the few years I've been playing adult games, I'm pretty sure only 3 I played were ever completed from start to finish - Dreams of Desire, Lab Rats, and Snow Daze. For those 3, there were probably 40 more that were abandoned in some state or another.
