You can always keep a look out for deals

I enjoyed it. My first romancing saga game. At first you get attached to your first character and set of characters but after the first one dies or passes of old age, you get used to cycling through leaders. It's a fun mechanic since it makes you change up how you play. I've read people really going at optomizing builds around the changing of king/queens and the skills that are passed down the line
