I just did a quick analysis of the way territory counts on maps impact on number of neutrals in the initial drop. I used this equation to rank them:
Score = Spare neutrals generated on 2 player, multiplied by number of finished 2 player games
plus neutrals generated on 3 player, multiplied by number of finished 3 player games
plus (same for 4p-7p games)
...
...
plus neutrals generated on 8 player, multiplied by number of finished 8 player games
all divided by 100000 to produce a smaller number (as they end up in the millions)
...where "spare neutrals" is the number of neutrals beyond what each player starts with (eg - 29 territory map is 9 per player, 11 for neutral, therefore 11 - 9 = 2 "spare" neutrals.
The table below shows
(Territory Count) - (Score) - (Perfect Distributions)
so...
40t - 33s - 4, 5
...means 40 territories - scored 33 - 4 and 5 player maps have no neutrals.
The lower the score the better
Top 20 Territory Counts
- 96t - 1.9s - 2, 3, 4, 6, 8
72t - 2.8s - 2, 3, 4, 6, 8
48t - 4.6s - 2, 3, 4, 6, 8
60t - 5.1s - 2, 3, 4, 5, 6
24t - 5.5s - 2, 3, 4, 6, 8
36t - 6.0s - 2, 3, 4, 6
84t - 9.8s - 2, 3, 4, 6, 7
90t - 11s - 2, 3, 5, 6
66t - 12s - 2, 3, 6
42t - 13s - 2, 3, 6, 7
18t - 15s - 2, 3, 6
30t - 16s - 2, 3, 5, 6
81t - 18s - 2, 3
57t - 19s - 2, 3
78t - 20s - 2, 3, 6
33t - 21s - 2, 3
54t - 21s - 2, 3, 6
45t - 22s - 2, 3, 5
21t - 22s - 2, 3, 7
93t - 25s - 2, 3
Keep in mind the scoring is based on the popularity of player-number games multiplied by the number of neutrals generated. So a territory count like 31 scores very poorly, as it generates 7 neutrals on 8 player maps (which are quite popular).
