7 seems reasonable and probably an easy change. As it is now, I never use luggers, not even in doubles; I tried them in some early games and quickly concluded, "totally not worth it!"
About the only time I could imagine luggers come into play is for assassin or terminator, where luggers give someone the chance to shoot across the board to a specific targeted opponent without need to assault non-targeted opponents. Someone who plays those types of games on this map may suggest that even then, luggers are rarely needed (would depend on the drop.)
cairnswk, I love everything else about this map, but I really did wonder if you'd put luggers at 10 neutrals as a ploy to lure noobs into trying for them
As it stands, Galapagos just does NOT have the balance of strategic options that your other maps have, and that's a shame; because something I love about your other maps is that none of them have, "one ploy only, sink or swim based on dice," game play. Galapagos kind of does
Another option, but much crazier, to make luggers more viable at 10 is to put at least double the regions between other bonuses and reefs (which would also double the regions between reefs outside of luggers, thus making luggers a more viable reach option).
Between the two, I'd suggest lowering the luggers.
If I recall, the option suggested before was to lower luggers to 5, I think that's a little too low. I think at the time I glanced at the thread but hadn't tried Galapagos so didn't vote; by the time I could vote, having tried the game a few times, the vote was over. 7 seems a good number.
