If procedural maps are generated from a random seed; you could potentially report the particular seed number, and then allow players to input it as a means of recalling and/or sharing procedural maps.

Sounds good.. gotta say I'm loving the generated maps, there's something very interesting about asymmetrical 3way/4way maps. Generated plains and forest maps seem to work the best (3way/4way).

From my perspective, the game itself is already very asymmetrical with the random card compositions you get each game.
That said, being able to use the asymmetry of the board as part of my tactic/strategy planning makes for some good fun!
