turn-based

It would be nice to have an option to pass G and ctx into the redact option in a long form move. The undoable property already has this option, so it should be fairly easy to implement. So it would looke like...

B: {
  move: (G, ctx, ...args) => {},
  redact: true/false or (G, ctx) => {},
},

For my particular use case, I have moves in my game that should normally show

Realms could start on some other planet order number than number 1.
Humans now start from planet 3, so other space race could also start on random number.

Expand the available list of system metrics. Around 10-15 new metrics (the most useful we can think of) is a good start.
