The days of a completely interlocking tapestry of maps from Nashkel to Baldur's Gate are behind us it seems. I think the EA map is supposed to be like if most of the BG wilderness maps were put together into a larger map, but because the map doesn't feel that large, and because we're never forced to reckon with travel times, it ends up feeling smaller.
