Lets get started!
Story:
Yes, and we say it about million times, your game will fail if you don't make a good story line. Here's an example how the story should NOT been made:'' You are a prisoner, you don't remember anything, you have to escape.'' THAT'S NOT A STORY LINE! You have to add many twists and a really long story line. Just like Mike said, sit down take a pen, paper and start thinking! Also DON'T use story line like this one:'' In this game you are lost somewhere on the earth, maybe in it. You play as UnKnoWn DuDe...blah... blah...'' THAT'S NOT A STORY LINE! it's a description for the game.
Graphical things:
There are some things you have to know about the graphical look of your game.
- Try making as many things own, not just taking off the resource page or asking somebody. of course asking somebody is bit better then taking from the home page.
- Add shading, yes, we know it is kind of hard, but just practice! I'm not a guy who can do the shading super duper uber awesome, but try it! Even I am getting better every-time.
- Also just editing Pierre's work is good, just make it look more like your own. Not just recoloring.
Gameplay:
The gameplay is a very important thing, don't make boring scripts - a message box and then show shop, script end, no that's not the best way to make a game. But remember, the scripting is only one part of the game the second is way better, the things how its done, like if it is a shooting game then the shooting. Another thing to remember - 001 is a action/rpg gamemaker, so those are the genres to make most easy. One time i tried to make an arcade like shooter, it was hard, and one day the project got deleted (i don't know why), the shooting was kinda messy, because, the game was a ''take cover, shoot, take cover''. If you really know the best way how to make a other genre game then that awesome.
Last tip: Work hard ;)
