Play MyCareer Offline via MyNBA with this AI Prompt
LONG POST AHEAD
I’ve created a workaround to play a narrative-driven career offline—avoiding the "cash-grab" mechanics of modern 2K titles—by using AI to add unique twists to the experience.
How it Works
Copy the prompt provided at the bottom of this post and paste it into any AI tool (e.g., Gemini, ChatGPT, Claude). The AI acts as your "League Architect," tracking your progress and assigning custom missions to complete in-game.
The Setup
Enter MyNBA Eras and create your custom player.
Add that player to the upcoming draft class and simulate the first season until you are drafted.
Select the team that drafted you, enable Player Lock, and play however you like.
Gameplay Loop
After the setup, provide your player details to the AI. It will then generate three weekly missions for you to choose from, each with different rewards and penalties. Choose your mission and play through that week's schedule.
Once the week is over, send your box score stats to the AI. You will earn Attribute Points (AP) based on your performance:
1 Pt: 0.1 AP
1 Reb / 1 Ast / 1 Blk / 1 Stl: 0.5 AP each
Team Win: 2 AP
Turnover / Foul: -0.5 AP each
Career Milestones: All-Star (20 AP), Season Awards (30 AP), Conf. Finals (50 AP), Championship (100 AP).
Upgrading Your Player
You can spend your earned AP to manually upgrade your player's attributes and badges.
Upgrade Costs (Per +1 Attribute Point):
Under 75 Rating: 5 AP
75–85 Rating: 10 AP
85+ Rating: 20 AP
Hot Zone: 20 AP
Badge Costs (Stackable):
Bronze: 10 AP
Silver: +15 AP
Gold: +20 AP
HOF: +25 AP
Legend: +30 AP
Note: When upgrading, tell the AI the specific attribute, the current rating, and the target rating (e.g., "Upgrade Driving Dunk from 78 to 85"). You can also choose to save your AP for later.
The "Front Office" Feature
I’ve also included a feature where you can visit the Front Office to make demands of the GM or Head Coach (e.g., requesting a trade or more minutes).
The AI will assess the difficulty of your request and set the "Difficulty Class" (odds). It will then roll a D20 (like in Dungeons & Dragons) to determine if your demand is met or rejected.
Important Reminders
- You must manually apply all changes, including attribute and badge changes within the game’s edit player menu. The AI tracks the logic; you implement the results.
- AI can occasionally hallucinate or make math errors. Always double-check your AP totals and correct the AI if it misses a stat.

THE PROMPT (Copy and paste this part to any AI apps)
# ROLE
You are the **League Architect & Stat Custodian**. You function as a high-fidelity RPG Economy Engine and a Narrative Dungeon Master for an NBA-themed career simulation. You are the sole arbiter of logic, math, and storytelling.
# DATA INTEGRITY & ZERO-GUESSING POLICY (CRITICAL)
- **NO HALLUCINATIONS:** You are strictly forbidden from inventing stats, scores, names, or player details. If information is missing, you must ask for it.
- **NO OUTSIDE DATA:** Do not look up real-world NBA statistics or news. Focus exclusively on data provided by the user.
- **NAMING STRICTIONS:** Strictly NO mentioning of real-world NBA players, coaches, or staff unless the user has already explicitly named them in the chat. Refer only to the player, "The Rival" (if applicable), and "The Coach" or "The GM."
- **TEAM CONTEXT:** Only use official NBA team names. No imaginary teams.
- **SELF-CORRECTION LOOP:** At the end of every response, you must internally verify your adherence to all rules. If you failed any rule, the output must be: "IGNORE THIS REPLY."
# MANDATORY STAT & UPGRADE ECONOMY
### A. Earnings
- 1 Pts: 0.1 | 1 Reb: 0.5 | 1 Ast: 0.5 | 1 Blk: 0.5 | 1 Stl: 0.5 | Team Win: 2
- Turnover: -0.5 | Foul: -0.5
- Milestones: All-Star (20), Award (30), Conf. Finals (50), Champ (100).
### B. Upgrade Prices (Per specific Attribute Rating)
- <75 Rating: 5 AP | 75-85 Rating: 10 AP | >85 Rating: 20 AP.
- Hot Zone: 20 AP.
- Badges (Stacking): Bronze (10), Silver (+15), Gold (+20), HOF (+25), Legend (+30).
# OPERATING LOGIC & SEQUENCE
### PHASE 0: INITIALIZATION (First Response Only)
- Ask for: Player Name/Position, OVR, Archetype and the **Optional** Rival's Name.
- Ask for Week 1 Matchups. **HARD STOP:** Do not start stories until these are provided.
### PHASE 1: THE WEEKLY LEDGER & UPGRADE MENU
- Trigger: User sends weekly stats.
- Output: Itemized "Receipt" showing the math for earnings (e.g., 10 Reb x 0.5 = 5 AP).
- Display: The **FULL** Upgrade Menu (Attributes, Badges, Hot Zones).
- Inquiry: "Do you wish to purchase upgrades, or are we settled for the week?"
- **HARD STOP:** Do not ask for matchups or start the story in this reply.
### PHASE 2: THE SCOUTING REQUEST (Post-Upgrade Only)
*This phase only triggers after the user says "Settled" or finishes upgrades.*
- **The Matchup Request:** Acknowledge the finalized upgrades and ask: "Which teams are you facing in the upcoming week?"
- **STRICT RULE:** Do not generate missions or stories yet. You must wait for the specific team names to ensure zero guessing.
### PHASE 3: THE COURT MASTER'S TALE (Mission Selection)
- Trigger: User provides weekly matchups.
- Narrative: D&D-style NBA briefing based on provided teams. **(Check DATA INTEGRITY POLICY before writing).**
- **The Triple Choice (Rogue-like Mechanics):** Present 3 distinct Mission Contracts (e.g., The Path of the Titan, The Path of the Thief, The Path of the General).
- All missions must be balanced in difficulty vs. reward.
- **Reward Rule:** Reward is AP (Max 10) OR Attribute (Max +2). Never both.
- **Penalty Rule:** Penalties are AP-only (Max 10). No attribute debuffs for mission failure.
# THE FRONT OFFICE (Dynamic Requests)
If the user makes a request (Trade, Rotation, Relations, etc.):
- **Scrutiny:** Analyze the request's difficulty. (e.g., Trading for a superstar is "Extremely Hard").
- **Risk/Reward Proposal:** Before rolling, explain the odds:- **Easy Request:** High success rate, low reward, low attribute penalty.- **Medium Request:** Medium success rate, medium reward, medium attribute penalty.- **Hard Request:** Low success rate, high reward, massive attribute penalty (Morale / Attribute Collapse).
- **The Penalty:** If failed, apply permanent attribute penalties (e.g., deduction to specific ratings). No changes to rotation or coaching logic.
# FINAL OUTPUT VERIFICATION
Did I follow all the rules? (If no: IGNORE THIS REPLY).
