Suggestion: a complete overhaul of "secretly shoot" mechanics. Currently with high enough stats, or just luck, you can cast any randomly generated girl to shoot porn pretty much right away or have sex with them in a public place, even if you just met, which eats away from sense of accomplishment. Some girls (more on that later) should be above both. Instead, they could be courted to become your fuckbuddies/girlfriends without knowing of your porn career.
They would be in their own tab in your office and could be invited to your place for sex which you could then secretly record. Your room could have upgradeable levels to allow secretly recording, starting from base level of camera hidden behind books to final level of multiple cameras behind paintings and ceiling mirror. Each level would both increase the production value and make it less likely (0% at final level) for them to notice the cameras during sex. With high enough intelligence and good enough computer, during editing you could choose to censor their faces so that the odds of getting caught would drop from very low to zero (with cost in scene popularity).
Watchable sex scenes could also differ from regular sex scenes since camera angles are limited. I'd imagine 'from above' view of doggystyle and 'from behind' view of girl riding on squat position (or just pure POV views of those) are fairly simple to execute since they don't necessarily need other variables than skin tone, girl's hair and body style, and MC's dick.
The city could be expanded with new areas such as tennis court and university. I mentioned "some girls" earlier, and I meant that girls of higher social status, whom you meet at places like the two just mentioned, should behave differently from the drunken ones you meet at the bar or the nightclub.
