It would be nice to have a recorder + movie-player for missions.
On the recording side, this needs just the initial configuration
of the map/actors/equipment, and then a log of all commands,
and maybe the results of dice-rolls.
The viewer would be just like the tactical part of the game,
but with VCR- and camera-controls instead of the HUD.
This would also help with bug-reporting and testing,
because everything that leads to a bug is in the recording.
And the next release could be checked against such bug-movies...
