Pitfalls

• Too much stuff
• Starting point
• Platforms and computing power
• Facebook
• Quality pressures
• Competition Unity, CryEngine

Suggestions

• Use Unrealscript when you want a new node
• Use Kismet to rapidly develop/rule out your ideas
• Multi sub-object materials
• Shader complexity
• Dynamic vs Static Lighting
• The foreach trap
• Single vs grouped objects (collision, render
  calls)
• Fill rate issues with particles
• Number of objects (cull distance, visibility
  range)
• Design level in UnrealEd, model/texture objects
  elsewhere
