This is an attempt at a reasonably comprehensive list of desired gameplay features, roughly categorised and split into small sections, with links to various sources of documentation and code.

Features that are largely completed are marked ~~like this~~.

Features that we probably want to complete for a first developer-oriented alpha release are marked with ^[A1]^.

Features that we probably want to complete for a later player-oriented alpha release are marked with ^[P]^.

Before working on a feature, it should be broken down into more detail and added as a Trac ticket (with a reference to the ticket added from this page).

"Old description" refers to technical documentation for the old simulation system; the new one has different features and different syntax, so use the documentation as inspiration and not specification.
