I was recently at Sotahuuto in Finland (a similar but not quite the same battle game), and I am bringing back a warning: extra long spears will change the game, and not for the better. The Finns have managed to make modular spears, allowing them to get up to 6m (20 feet) long. Their combat is a lot more static than ours, with shieldmen being almost entirely defensive. It's still fun, but not nearly as fun as current Beledag fighting. I'm going to institute a 3m limit on spears in my realm to avoid this trap.
