If you enter New Eden Holdings after returning home, and talk to Reception, you'll be kicked out, and you'll have the incorrect UI. The limited days UI instead of the Public Opinion UI.
What? Playing all HTML real porn games? Ha ha! No, that would be crazy. I mean, why would I limit myself to real porn when there are so many great HTML games without real porn, such as Looking Back, Free Cities (pregmod), The Pills, The Weekend and many others. And let's not forget some classic Ren'Py games such as The Roommate or Holiday Island. That being said, Gateway and Sluttown USA are my current favorites and they do use real porn.
I have seen you in Gateway, Sluttown, Simlife, College Daze and Just one more Chance. That's why I said that.
As for the ones you named other than the Roommate I haven't heard of them.
