Love the blog. Well constructed lists. Only list missing is a sort of 'Lost Tribe'. If I might make some suggestions...
I have a large number of Celtos miniatures (bought in a B&B) armed with bows, spears, swords etcetera. They make excellent lost tribe figures, just the right amount of fur and beards and attitude.
To my mind the Zulu list in HVF for a Lost tribe would work with some tweaks.
Veteran, Bloodied and Unbloodied transfer across beautifully to old (grizzled), mature and young warriors.
Allow warriors to have a choice of swords, bows and axes alongside spears and clubs, but no rifles or other modern weapons.
Use the Inyanga stats for Shaman characters with perhaps more mystical power options.
Have a berserker option for the really bearded warriors.
And there must be an option for a pet Sabre Tooth Tiger!
I'd use the stats for a Lion/Tiger with perhaps an AR 9 and tough to emphasize its primeval power.
I look forward to using these lists soon.
