The PWO and noswitchonpickup should be supported
These will not be implemented in odamex, as this is not part of the scope of the project
Also it should be great to record a demo without joining a game, in this way one can play on a server and record a demo on another in the same time.
This would require the implementation of spectator code, which currently does not exist and demo recording isn't implemented yet, because a custom format needs to be designed.
