I thought I'd give this newfangled custom map contraption a whirl, and here are some of the results, collected into one thread for the benefit of YOU, the customer!
To start with, Sanctuary (2) and Sanctuary (4), two and four player versions of the same concept. All players start in a very regular cluster of planets, quite dense, all easily conquerable - but their opponents are quite some way away. Minimum of three rounds in the two player version, minimum of four rounds in the four player version. The two-player version comes down to pure guesswork - where are your opponents ships stationed, where will they attack, and when? It's pretty much the heart of Mayhem Intergalactic, but may be too chancy for some people to stomach.
Sanctuary (4) is much more chaotic, because the addition of two extra players leads to far more "Oh dear, somebody just took my unprotected flank" moments. I'm considering putting a single planet - or cluster of planets - in the middle of Sanctuary (4). That wouldn't do for the two-player version, because whoever gets the centre planets will always be able to hold them, but with four players to take down anyone who shows signs of a lead, it could work much better. Thoughts?
