I've always felt that hexes were easier for laying things out on the gaming table in terms of movement and areas of effect because you can do more angles without doing counting tricks. Squares however are easier for laying out structures and buildings since human society seems to have settled on rectangles for most of our floor plans. I always end up making a mistake translating a map that uses squares in published material over to a battle mat that uses hexes.
Is there anyone that prints a battle mat that has hexes and squares on the same side?
