you arent sounding cocky really, i also have been drawing stuff since i was little, my parents wanted me to go into the art field, but i got into computers instead.
Unfourtunatley my insparations are so amazing i often try to match them and overestimate my own abilities. Like i still cant come up with a good storyline since i am trying to write something awesome epic and original. as in terms of a storyline, my insparations are final fantasy games, full metal alchemist, star wars, Samurai Jack (not as much the story as the visual style and the atmosphere of the world under Akus rule (btw sam Jack is heavily influenced by star wars)) few concepts from Dragonball Z and a bunch of other shows and movies. But i want to make actually original storyline, so it dosent look like a copy of something and still be amazing and epic. What i am doing is writing downd miscellenios parts and concepts story patterns from shows and movies that inspire me hopefully so i cane edit/ remake and adapt them to my story (thats not plagirism, every good show/movie stole a few small pieces from some other work)
Still, i cant think of an original epic storyline, even tho, i already have a good solid concept for a backround world of the game. i even have less troble thinking up good charecters and backstories for them. But my stories either turn out to be totally rubbish, or i cant figure out how to develop good rising action.
I think my problem is, i cant find the concept of what to build my story around, or cant think of a good conflict and how to develop it.
Dont get me started on music lol. its the same as the story thing, cant think of something that sounds original and awesome, everything i try to write always resembles great works that influenced me. And i am not aiming for high quality orchestra too, i use MIDI creator. Judging from many great old games, Midi music, if done right can be almost as amazing as big movie soundtracks.
The rest is just a bunch of hard labor. Spend tons of time modeling and animating everything. Even here i am aiming pretty low as i am gonna do low poly style models like the games from mid-late 90s (thef the dark project, Dark forces 2, FFVII, Gothic1)
and finally the hardest step programming it all.
But i cant really program or make models if i dont have the story in mind. Since story decides key elements in the game, such as charecters, location, dialoge, battles, enviroment/ atmosphere etc.
Like i can model a town built in a large abandoned trainstation called train-town, but i dont know if ithe charecter will go there or not because i have no planned out storyline so my train town might be completley useless in the end.
Also, modeling just a train town with nothing in mind is counterproductive as when you do think of where in the story to stick it, you might have to remake parts of the town to suit your story better and its all unorgonised and might end up being somewhat crappy.
However, if i have a story and i know whats gonna happen in train town, i will model it exactly as needed fit the events that might take place there. Like if there will be some boss fight in this town, i would proboly make a large clearing in the middle of the town with enough space for fighting and so the giant mechanized tank-robot enemy boss has enough room to efficientley kick your ass
Holy crap did i just write all that? i do that sometimes... Well maybe this essay will give you some ideas.
dont hate people who rip you off,cheat and get away with it, learn from them
