My Role

As a Game Designer I was responsible for the economy & progression for Sacred, as well as difficulty balancing (defining stages, waves, monsters).

My Responsibilities

  • Established Economy Balancing: Setting up exhaustive balancing sheets (both Excel and Google Sheets) including all the functions, projections and diagrams to get a good grasp of the economy, difficulty and player progression
  • Sources & Sinks: Modeling sources & sinks (permanent & temporary) for all currencies (soft currency, hard currency, evolution materials, etc.)
    • Income vs. Cost breakdown and projections
    • Currency source/sink projections for all major features: Quests, Gacha System, Stages, Merchant, Harvest Missions, Item sell, PvP fights, Daily login calendar, VIP system
    • Additional sinks: Skill cost progression, Item prices, Spirit upgrade costs, Item enhance costs, Item evolution cost, Rune forge costs
  • Difficulty Balancing: The goal was to guide new players, while progressively ramping up the difficulty.
    • Stages: Structuring the layout of individual stages, setting up waves and monsters
    • Waves: Building “sets” of monsters and spawning them in a cohesive manner
    • Monsters: Creation of monster & boss types, definition of their stats (HP, damage, armor, etc.) and skills (active and passive)
  • Play-testing: Thorough and focused play-testing of the story campaign to ensure a smooth progression of the economy and difficulty
