I'm trying to work my way back through the series, at least as far back as the games keep being enjoyable. Due to playing on an emulator, I'd rather make the experience of playing 3 as easy/quick as I can. Particularly grinding affection, since in my experience that's the slowest thing in these games.

Any easy way of "breaking" RF3? I'm mostly interested in characters and story, so anything that makes it easier to romance the girls, or just easy ways to make money and make me not worry about it are what I'm looking for.

Is it still possible to date everyone at once before settling for marriage? Anything to be aware of in that sense?

Regardless, any tip or trick, or important difference from 4/5 in general is greatly appreciated!
