bitburner-src/doc/NEW_BN_GUIDELINE.md

Promote:

• New mechanic
• Coding problems based on NP problems. This makes solution that are easy to implement inefficient and solutions that are hard to implement efficent. (eg. Stanek)
• inter-mechanic synergy
• Simplicity (eg. Stanek, Hashnet. bad example: Corp)

Avoid:

• Failure conditions, it's very frustrating to revert several days worth of progress.
• Making existing mechanic harder. This makes it hard to port the content to other BNs.
