The latest (20150609) version of the Less Is More Graphics Mod available here.
This Mod's guiding principle: Less Is More!
For your convenience, the LIMGM is packaged in the form of a JSGME mod package. If you don't use that mod enabler utility (you really ought to!), you should know that among the many folders included in this latest version of the Mod, just two folders are populated:
[*]Gfx > Arrows
[*]Gfx > Hexwar
In this version, look for the modded files there, and only there.
A recent screenshot, showcasing some of the most important features of the Mod:

Which do you prefer?
This:

Or this (info question marks, no-move red Xs, done-move check marks all 50% smaller than stock):

(The graphics look better in the actual game than they do in the compressed JPG images displayed here.)
If you prefer the latter image, download this file and unzip in your Brother Against Brother > Gfx > Hexwar folder. Backup your original files -- HW_DirectionArrows.pcx & HW_DirectionArrows_a.pcx -- first!
This is just a quicky first effort (not perfected). In addition to
[*]reducing (or enlarging!) graphics elements
we can also
[*]give them a different color
[*]desaturate them
[*]sharpen them
[*]reposition them within the hexes
and/or
[*]replace them with entirely different images (e.g., thinner movement & firing arrows)
and even
[*]blank them out entirely so that they don't show at all!
Let the user modding of BaB graphics begin!
