I don't usually go for the more cartoonly looking games, but this one just entertains and keeps me coming back. I can't share in all the hate for Cody - just ignore him, it's the women you're interested in - but apart from that I'd go with what's been said.
Vae Victis. There are walkthroughs and hints, but you can choose to ignore them and work them out for yourself. Peasant's Quest includes some as well.
Toro 7 had one or two.
I haven't played Deviant Anomalies so I don't know if they're the same type of puzzle.
There is a path where she's pregnant, though I haven't played that one. There's certainly a path where Sandra (as you say, the boss's niece) is pregnant.
The Ashley (ginger sister) endings include one where she's pregnant.
Comes back to the quality of the game. If it's really good, the branches and paths are likely to be different and it's like playing a different game, or seeing the same events from different perspectives. If I'm really enjoying a game then I'm happy to play it on different paths, sometimes...
One hundred percent. It would be very dull if we all liked the same things. I generally look for the highest rated games if I want to start a new one and some of them - Mist was the worst - just don't do it for me at all. This one was kinda 'meh', but it keeps getting good reviews, so some...
That's what the tag system is for. I have found myself deleting a few which were just too poor or too revolting, but I haven't done them the service of recalling their names.
Not usually my thing either but Monster College has turned out to be really good. Peasant's Quest is starting to have a few as well although I have avoided a couple which were just too gross.
