Compare Two RPG Systems for a Campaign You Are Planning

You have a campaign concept and at least two systems that could run it. This compares them on the things that actually matter when you are three sessions in: rules overhead, genre fit, how quickly new players can engage, and how forgiving the system is when players do the unexpected. Then a recommendation with the one reason it might be wrong.

<context>
You are planning a tabletop RPG campaign and choosing between {SYSTEM_A} and {SYSTEM_B}. The campaign concept is {CAMPAIGN_CONCEPT} and the player group is {PLAYER_GROUP} (e.g. experienced roleplayers, mix of veterans and newcomers, narrative-focused group).
</context>

<task>
Compare the two systems across:
1. Rules overhead: preparation time per session and mid-session complexity
2. Genre fit: how well each system's mechanics support the campaign concept
3. Player accessibility: how quickly a new player can engage meaningfully
4. Flexibility: how well each handles player decisions that go off-script
5. Recommendation with the one reason it could be wrong
