Puritans &... Pleistocene?

A half-formed thought inspired by notes on The New World for SBVD, by re-reading Marvel's 1601 comic, and by a thread at alternatehistory.com entitled No Megafauna Extinction (in between threads entitled "Cato's Cavalry" and "A Long and Flowing Whig" - those AH guys are nuts. Erudite, but nuts).

So Daniel Boone crossed into the bluegrass country of Kentuckee. 
Only to happen upon...

From the originating thread:

I see there being a market for Glyptotherium and D. clavicaudatus shells as curios in europe, along with Ivory, utterly massive furs, from Arctodus, Castoroides ohioensis and C. leiseyorum, and various fibers from all the different Camelids. F***! It'd be like a treasure trove for anyone stupid or desperate enough to try and set up shop there.

Hell, in the Caribbean, where things aren't as deadly, you've still got miniature ground sloths, Flightless Owls and rather interesting parrots (that might revive the fashion for parrots among the nobility back in Europe,) plus all the stuff that drove settlement IOTL.

We have scads of Pleistocene beasty stats in B/X; we have our grungy, low-powered D&D modcops; and between ckutalik's Hill Cantons Domain Game and Autarch's forthcoming ACKS we have our colony-builder systems. This is just crazy enough to work!

And lo! The gods did look upon the ravings of the fog-addled bogmonkey, and decreed that Mammoths and Muskets (or Brutes & Buckskins? or Settlers & Smilodons?) was a stupid idea, but one that might have legs, so don't knock it on the head just yet. :)

Edit: You know, I should probably split all this non-Vaults stuff off into another blog. Or would that just be annoying and fiddly?
