I remember buying this like 5 years ago. The early girls aren't very complex, you say get naked they do what you want etc. But the developers started turning some of the girls into full fledged dates where you actually had to speak with them to get them to do shit. For example: Initial Release Girls: "let me fuck you" she instantly starts stripping followed by a sex scene... Newer Girls: "let me fuck you" she replies with "I dont know you well enough" or "who the fuck are you"
Think of this program as amateur porn that's been scripted as a date or in some cases a tinder hookup if she's easy. The older girls really aren't worth downloading, but the new girls should have some fun in them.
