I just need a little help. How do I write a good description?
If you can give me some pointers on how to write a description of a storygame or show me an article on how to write one.
You mean a description of your game? The idea is to give a brief, grammatically correct summary of what your game's about and at least some idea of what the player will be doing in it without giving away spoilers or overloading potential readers with too much information.
My opinion is same as Kiel.
