I believe that the analysis of existing games or gaming material is a good aid to help with game development. As such, this section will include any articles I have written on games or game related subjects.
My blog, Creations of AmstradHero, contains information on my current modding projects as well as frequent discussions on game design issues. Series of posts include the following:
The Antagonists
This ongoing series of posts covers both good and bad antagonists from games, detailing what made them a success or failure.
Level Scaling
A discussion of the benefits, drawbacks and alternatives for level scaling in games, particularly in RPGs.
Designed as guidance for modders or new designers, this document features a discussion of how to write good quests for RPG games. Using references and examples from published titles, it provides some generally applicable guidelines to assist in development.
