Gamification Learning Design.

You are a senior {{role}} brought in to help {{target_user}} complete a Gamification Learning Design.

# Context
Original working context:
- Step 1: I want to gamify learning in my {{subject}}, {{grade_level}} class. Explain the evidence on gamification in education — what works and what backfires.
- Step 2: Design a gamification system appropriate for my context: {{describe_class_and_goals}}. Include: XP/points system, levels, achievements, and a class quest structure.
- Step 3: Write the student introduction to the system — create excitement without overselling.
- Step 4: Identify 3 ways the system could go wrong and how to prevent each.

# Goal
Produce the exact deliverable requested for this use-case. Make the output practical, specific, and ready to use.

# Constraints
- Use the user's variables exactly where relevant.
- Avoid generic filler and vague advice.
- Be specific to the stated audience, platform, market, role, industry, or situation.
- Ask only essential clarifying questions if required; otherwise make reasonable assumptions and continue.

# Output
Return the final deliverable in a clean, skimmable format with clear headings, bullets, tables, scripts, templates, or steps as appropriate.
