Hi Ian!
Thanks for your help.
I played around with the map creation of GamesMasterNG and the distribution of the planets on the map is MUCH better.
The problem with the maps the GalaxyNg server creates is that there are large spaces without planets and then there are these 3 or 4 planets really close. This may not be a big problem but it just looks so wrong

.
But I also ran into some problems with the GamesMasterNG:
You wrote that there is no documentation and I have some trouble understanding what some of the options do.
Design Types are pretty clear except for 'GalaxyNG random'? No idea what that does.
How does the Seed Type and the Seed sizes influence the map?
Something seems to be wrong with the OnCircle Design type. Screenshot shows the problem (again tiny5 values). Are the seed values wrong??
GamesMasterNG crashes when changing the second core size field in the template editor (Run-time error '9' Subscript out of range). Not really a big problem, since I can edit set the sizes when adding players.
What look are you wanting to generate for you galaxy?
The Tiny5 values are just a test case since I knew they should create a nice galaxy.
I tried several different types of galaxies up to now. But I don't seem to be able to create a nice one. I am basically looking for a layout with lots of big empty planets and only very little to no stuff planets so the players can expand fast and build massive fleets with lots of battles (since the big planets are right next to each other). But I can't seem to get it right. One problem is that the planets created have very little ressources (in a test game I created most of them had 0.3 - 0.6). Then I ran into the problem with the distribution of the planets (those clusters get really bad when you add lots of empty planets ... but thats obviously due to poor code in the actual server).
Since your games always seem nicely balanced: Is there some general advice you can give me for setting the values for size, race spacing number of planets, ... (something like 'The GalaxyNG GameMaster Guru's guide to creating galaxies '

) or is it just trial and error?
And one other thing: Did you ever create a team game? According to the server manual (of the original server) this should be possible, but the server always crashes when trying to create the game.
