I’m making an RPG, and I need a guide on how to make one

I genuinely only know how to make character bots, but I’ve wanted to make an RPG for awhile, but I’ve not had a good idea before and I don’t know how to make one

Basically I don’t want my first RPG bot to be straight booty cheeks (the bad kind of booty cheeks, not the good kind of booty cheeks)

If there is a guide or something, I would appreciate it, otherwise if there isn’t: I would just appreciate some tips or something like that
