> They need an editor who will go through and identify the puzzles that must be solved through brute force

Barely any adventure game has a puzzle that requires brute-forcing. The problem is rather that sometimes players don't have the same kind of thinking as the developers.

This issue can be aggravated if the player comes from a different culture or is playing a translated version of the game; for a famous example: the "monkey wrench" puzzle only works if the player is used the the US-American English name of the respective tool.
