This product goes a long way toward handling languages much more realistically than the standard d20/OGL rules. I really appreciate the work that went into this product. However, when I tried to use these rules in a 3.5e campaign, my players and I found them to require rather more bookkeeping than we expected, so it didn't work out as well as I had hoped. The idea may be better than the practice here.
