- Development Hell: The last version, 3.4.3, was released in 2003. Apparently, the Dev Team is still actively developing it, but it is developed under the "cathedral model" of open source development where the development source code is not put up for public access. Unless it is leaked.
- Long Runner: The game began as a more sophisticated version of Rogue, named Hack. It gained the "Net" part of its name when various contributors from around Usenet began adding their own features to the source code base. If you've ever seen the source code, you know it looks like something that's been edited by committee.
- Unintentional Period Piece: Look at Shout-Out list above. Was this made in the 80s or what?
- The Wiki Rule: There's one here.
