I was concerned that there were no maps designed specifically for five players, as playing a random map for six players with only five leads to a huge start advantage for some factions.  So I created some balanced five player maps with GalaxyForge3, and they have been added to the maps for download from this site.  All the maps have a fixed start position similar to the random maps, with randomised planets making up the bulk of the map.

'Safeguard' is based on the size of a four player random map, so is suitable for quicker games and rushing, as is 'Sine Qua Non'.

'Pentameter' and 'Prevalence' are based on six player maps, and are suitable for longer games.

'Trigonometry' is a map for three players, based on a four player map.

I've tested all the maps, any comments welcome.  I've made a couple more since, also I'd revise any of these if it would be useful.

There were a couple of threads recently about issues with the map editor- I had no problems with GalaxyForge3.
