1. Getting an idea
-----------------------------------------------------------
First of all, before even starting to get ideas... Decide what kind of game you want. If its hard to chose one, then get inspiration from other games. After you have determined the type, then you may start.

Take up a document in notepad, write everything that comes into your mind when you think on what game you would want to do. Then, in another document, write what comes into your mind when you think on what a game shouldnt be.

Now you can see what you can implement in the game and what not to. Then sort out all the bad ideas, or the ideas that are to hard or even impossible to make in TGF or MMF.

Write a design-document of the game, there are some other articles about that i think. It should include how the game plays and a more detailed view on the story, i think! Now, thats just how i use to do...

When your done with idea-ing, give it to some friends for commenting maybe. If they say its a good idea, start!

MAKE THE GAME... GET COMMENTS... BE HAPPY AND PROUD!
