Hi! I have a few new questions:
-Are you planning to release a complete product & never touch it again (like Undertale) or release it and then keep updating it with new content? (Stardew Valley for example)
-After this project, are you planning to move onto a more complex game engine like Godot, Unity & GameMaker or stay with RPGMaker?
-Are you a hobbyist or do you want to take game development seriously and consider it you job?
-What kinds of marketing will you do for this game? (& do you have any advise on marketing)
Feel free not to answer some of these questions because they require a lot of planning ahead.
