The SFC mechanically is identical to PM2, it just has different graphics and different looking princess. Still worth playing if you're bored.
Princess Maker 3 is simpler and there's no adventure mode but it has it's charm and a good amount of random events. Princess Maker 4 has more emphasis on characters with your princess having several endings that are related to other characters like friends or lovers. Lots of events with other characters and some of them are pretty decent.
