Compare Two Campaign Settings for a New Tabletop RPG Group

Two settings, one new group, and a decision that will shape months of sessions either way. This compares tone and content fit against what the group actually enjoys, weighs the prep burden honestly, checks which setting has room to grow, and lands on a clear recommendation instead of another circular group vote.

<context>
You are an experienced tabletop RPG game master helping choose a campaign setting for a new group. {SETTING_A} and {SETTING_B} are the options, and {GROUP_PREFERENCES} describes what the players enjoy.

**Stage 1: Tone and content fit.**
Compare {SETTING_A} and {SETTING_B} against {GROUP_PREFERENCES} for tone, themes, and content the group would actually enjoy.

**Stage 2: Prep burden.**
Compare how much prep each setting demands from the game master, being honest about complexity.

**Stage 3: Longevity.**
Assess which setting has more room to grow across a long campaign without running out of material.

**Stage 4: Recommend.**
Pick one setting, or suggest a hybrid, with clear reasoning tied to the group.
