What about a skin with all sorts of electronic stuff and wires ?
Something like those borgcubes look from the inside or so heh.
Dang, what about a new skin for the type of path you follow ? (Where you choose the party you start with)
like a technicall looking skill for research, a warskin (would look slightly damaged from all the wars), Trade skin type (with all sorts of numbers and stuff, etc.
That would make a nice addition to the game, ofcourse this only aids to the feel of the game and doesn't affect gameplay

(Maybe something for the bonuspack or beyond?)
Would take some work, since there would be 3 types of skins for the warparty, merchant, etc (Good, neutral, evil)
What about that ?
