About this model
"Create a Machinations diagram simulating the Free-to-Play (F2P) loop of the Hearthstone economy. Model this using a weekly time step (representing one week of play).
1. Resource Generation (Inflow): Create a Source node labeled 'Player Time/Effort' that flows into a Pool labeled 'Weekly XP'. Add a Converter that turns 'Weekly XP' into a Pool labeled 'Gold' (assume an average F2P yield of ~600 Gold per week) and a Pool labeled 'Reward Track Dust/Packs' (assume ~200 Dust equivalent per week).
2. Pack Opening (Probability Gate): Create a Converter that drains 100 Gold from the 'Gold' pool and pushes 1 unit into a Gate node labeled 'Pack Opening RNG'. The Gate should probabilistically distribute to Pools representing card rarities:
Common (4 cards, 90% chance each) Rare (1 card, 100% chance) Epic (20% chance of replacing a common) Legendary (5% chance of replacing a common) 3. The Dusting Loop (The Sink/Tax): Connect the Common, Rare, Epic, and Legendary Pools to a Drain node labeled 'Duplicate Protection / Dusting'. This Drain must flow into a Pool labeled 'Arcane Dust' using these exact conversion rates:
Common = 5 Dust Rare = 20 Dust Epic = 100 Dust Legendary = 400 Dust 4. The Crafting Loop (The Source/Value): Create a Converter labeled 'Crafting' that drains 'Arcane Dust' to produce cards. Use the exact inverse crafting costs:
Common = 40 Dust Rare = 100 Dust Epic = 400 Dust Legendary = 1600 Dust 5. Meta Deck Goal (End State): Create a Pool labeled 'Viable Meta Deck' that requires a specific input of cards (e.g., 15 Rares, 5 Epics, 3 Legendaries) to reach a capacity of 1.
Please set the simulation to run automatically so I can observe how many weeks it takes for the 'Viable Meta Deck' pool to reach its goal relying purely on the Gold - Pack - Dust - Craft loop, highlighting the 4:1 dust value loss."
