I've not ever considered special dice or tape measures...
BUT I am extremely keen on having a clean, neat, good-looking tabletop. I HATE seeing games all cluttered with dice, rulers, cards and rulebooks on the table, so that you can't actually see what's going on. It drives me mad!
I just can't fully get into a game unless I go whole-hog. While this is fun and enjoyable I've found myself suffering when I play a game half-assed...which concerns me. :D Is anyone else addicted to the accoutrements of the experience?
Furthermore I made a befriended and very skilled bow maker make a special ruler for SAGA: A crossbow bolt with markings for very short, short, medium and long range according to the rule book.
