More Words, Deeper Hole

Stirling's setting was in an alternate-history where the 20th-century island of Nantucket (population 10,000) was thrown 5000 years back in time. They used their remaining technology to build sailing ships, single-shot rifles, and bayonets, and then proceed to get involved in a land war in Asia, fighting opponents armed with spears and swords. So, the events in the story pretty much lined up with the historical record - just moved a few thousand kilometers northeast.

Huff's setting was on a planet of aliens with a high birth rate. Their dumb and aggressive spawn were released into wilderness areas to fight and cull each other as they developed towards adulthood. A diplomatic delegation from other planets (including Earth) was sent; it had a multispecies armed forces unit attached to it for security. The security force's transport crash-landed in the middle of a wilderness area full of aggressive, hostile juvenile aliens. They took shelter in some abandoned buildings, and had to defend themselves until help arrived.

Read Stirling for the setting, Huff for the characters.
