Oh cool, I'm playing the first one right now. I had no idea what I was doing the first go so she just ended up a house wife, but on my second go I think I'll corrupt the shit out of her and turn her into the biggest raging slut in town just because I'm curious. How's PM3 by the way?
There's good and bad stuff, but overall I really like it and it's addictive as fuck. On my first try she became the first female royal scholar, then a government worker in two play through, the princess of the Rabbit Kingdom, a millionare's wife and then a miner.
Good
-You no longer have to pay for her food which took a big chunk out of my funds in Princess Maker 2.
-The graphics have gotten better and you get to see some of the characters from parts 1 and 2.
-You can speed through her schooling and work sessions by holding the left mouse button.
-You can plan her schedule for as long as you want. You can do it one turn at a time or plan it ahead as far as you want. You can also look back at your previous choices to see what you've done and what works or not.
-The gameplay is quicker and still has the Princess Maker charm.
-You can pick the kind of job you want which will determine your budget, the amount of extra yearly money and your daughter's abilities and mood. Caution: if you pick the traveler, you start out with a lot of money, but you get no allowance.
-The moods (happy, arrogant and rebellious) all have their own art, dialogue and strengths and weaknesses. Certain jobs will not be available to the rebellious daughter, but she will do really well at some jobs, like mining. The arrogant daughter will be lazy at certain jobs while better at others.
-There are other princes to marry than just the human one. The Rabbit Prince is a fun one.
-Your rivals can do more and you can even become friends with them and give presents on each other's birthdays.
Bad
-The festivals seriously lack variety and are all pretty much beauty pageants.
-There's a weird buzzing sound that comes during one of the season that you can't turn off.
-The intro and ending texts are in white and a bit tricky to read. Sometimes the text will go off of its panel or not wrap around properly.
-No adventuring or visiting the palace. Though you can get a royal maid job if you meet the right requirements.
-To avoid possible crashes, save early and often.
