That’s a good question, there are usually four ways to arrive at a story . . .
- You read, or learn something weird, important, or etc etc
- Personal experiences, doing stuff in life, some have a journal, quite useful for also writers
- You make a setting, say ’ Lord of the Rings ', and then write stories there
- You have a crazy idea, inspired by a character, or something you saw some other place
- There’s some ’ trope ', or recurring idea, aka the seen-often stuff, and you make stuff over that
My advice is perhaps this, writing either story, a culture for a video - game, or then important characters // important quests is perhaps the fun stuff, or something you want to set extra resources aside for, the problem is that writing good, or relevant fiction is rather difficult, and one ( usually ) needs a good idea, or starting - point, it sounds like you already have that, a place where stuff happens, there are waves of enemies, it’s a good question why the character is there, or even cares, could it be his place, the monsters threaten his house, or other people he knows, then the character has to make a decision, flee from the monsters, somehow fight them, or also find a diplomatic solution . . .
One of the best ways of writing stuff, is asking quite simply, in that situation what would a normal person, or even the writer himself, or her then also do, or how to react, for me writing characters, or a coherent setting that makes sense, that’s more than just ’ art ', or ’ random ideas ’ takes years, and it’s never easy, for me stories, or character usually start if have learned something important, or perhaps cool, or some personal event, or life - stuff . . . .
This book is quite a good read, it’s also written by Mr. Stephen King, one of my favorite writing books . . . .
If you could bit advice, asking other people how to write, most people learn the stuff in school, at least a short essay, or what to write is bit weird, mostly because the entire point of writing is that it’s YOUR writing, characters, or ideas, and that’s what people want to hear, or whatever you think is important, or at all, one of the perhaps best sides of Unity, writing, or art etc etc, is that it’s your ideas, or what is important to you, don’t let that go to waste, or at least practice, and perhaps make something original, for me using those random - gen sites for making stories is bit the same, overall the reason people make art, or then classic writing, that is perhaps a bit different niche, is that it’s their art, or original stuff, my advice is see writing as a gift, or your chance to ’ shine ', and add that to your title at your own pace, or start by making a title with no story, then figure that later . . . .
( why did start by writing four ways, then it was five, that leaves you guessing, and you’re now interested in my story, or also what-happened, see what did there . . . . )
