Some more advice for those who want to emulate a earthbound like style:
5. Draw your own art. Even if you aren't the best artist, try to develop your own style and skill in your art. Took me 6 years to draw better than my first attempt at a rpg.
6. Don't worry about making a perfect battle system. sometimes the default 2d/3d battle system is ALL you need. If you WANT to add more features then I encourage you to ask how to make them in The RPG developer Bakin discord! Ask for amalgamash, one hell of a man too!
7. Try to keep the main villain involved along with minor villains. For example: Evil lord Buttfacé steals the breakfast jewel of deliciousness and occasionally can be seen at random restaurants enjoying a refreshing iced tea while committing minor crimes and taunting the heroes. A miinor villain could taunt the heroes and steal a valuable item from the party after a fight.
have fun with it, i am eager to see your games!♫
