Savegames

This page is transcluded on Map format.
Problems with the existing savegame format:
 - they are big
 - they are many
 - they are disconnected from rulesets, giving errors or undesirable behaviour in saves when the ruleset changes
 - loading of savegames is not streaming but requires vast sums of memory (up to 100 megabytes)
 - load of big games can be quite slow
New features we want:
 - replay
So how would a future, better savegame format look like?
