Plotline sounds similar to
Patriarch? How is it different?
Edit:
So after playing one run of it (I doubt any of my choices mattered), I can say it's.. rough..? Plot is very similar to Patriarch, as you even have to run internships before getting handed the fortune. The playstyle is very different though. Where Patriarch is a semi-open world, this is very much a VN.
For a first version it's OK. It's rather low on sexual encounters and you don't even have a choice in them, they just appear in the story. The size of 800+ MB is due to images being big .gifs, that don't pop up for a couple seconds. Definitely should be converted to either .webm or .mp4. Grammar and spelling are good overall, even though I suspect the author is not a native English speaker. Formatting is pretty bad though. Too long passages and missing spacing between different people's lines makes it sometimes hard to read. On top of that, the conversations themselves are really shallow (I know, what'd I expect from a porn game) and predictable.
TL;DR: It's a VN version of Patriarch + Little content, maybe 30 minutes if you read everything
