Game development is a large process. In your experience, how are the total hours for releasing a game divided over the following major areas. I believe this is useful because few people (none?) are really good at all the areas, so this helps me balance the cost of items I'm not so good at when estimating the complexity of creating a game.

• Modeling and raw asset creation (textures, audio)
• Level design
• Gameplay design
• Programming
• Testing
• Marketing
