It's a minor thing; but damage for the Shortbow is d6 vice d4.
Vargr: I'm not sure I'd say a 6 or 7 is crippling as the penalty is still only -1 (6-8: -1, 4-5: -2; 3: -3); though any chance of rolling under an Ability score would be pretty tough!
Actually, while I don't know them personally; I've seen any number of BECMI pbp Games and session reports from people who love this Edition use 3d6; in order....letting the rules pretty much dictate the type of character to be played. These folks' are also really hardcore about using the whole "Points can be moved from Strength to Intel if a Magic User or vice versa for a Fighter and Constitution can NEVER be changed, etc., etc. rules.
I don't know anybody who really uses random HPs at 1st Level though...I know a couple that have people roll; and if they roll less than 50%; they're automatically bumped up to the half-way mark. Most people I know just use Max HP at 1st Level though.
Epichicken: If I forgot to say it earlier....welcome aboard!
