Test example (output):

Crossroads of Civilizations: Card Game Framework Design

  1. 1.  Game Overview
  • Game Introduction : "Civilization Convergence" is a collectible card game with the theme of the integration of ancient civilization and modern technology. Players will play the role of "cross-era researchers" to collect, study and integrate ancient artifacts and modern technology to create unprecedented power.
  • Core concepts : strategic matching, civilization integration, knowledge exploration
  • Target audience : High school students and above, players who like strategy games
  • Game features : unique ancient and modern fusion mechanism, team cooperation mode, and variable strategy combinations
  1. 2.  Worldview setting
  • Background story : In 2150 AD, scientists discovered a huge underwater ruin in the South Pacific - Atlantis. This highly developed ancient civilization had technology beyond the present, but mysteriously disappeared overnight. As the ruins were developed, humans began to discover various mysterious artifacts, called "source devices". When these source devices were combined with modern technology, a new energy that changed the world was generated - "fusion power". Major research institutions and expedition teams competed to collect these artifacts and study their power.
  • Main factions :
    • The Guardians : An organization of scholars dedicated to protecting ancient relics
    • New Era Corporation : A conglomerate seeking to commercialize ancient technology
    • Balancing Parliament : A Governmental Organization Seeking Harmony Between the Past and the Present
    • The Mystery Order : A secret organization that studies the mysterious powers of ancient civilizations
  • Important elements and concepts :
    • Source : An artifact with mysterious power left behind by ancient civilization
    • Fusion power : the energy generated by the combination of source devices and modern technology
    • Awakeners : Special humans who can activate the power of the source device
    • The space-time interface : a special space where the power of ancient and modern civilizations converge
  1. 3.  Core Game Mechanics
  • Basic rules :
    • 2-4 players battle (also supports 2v2 team mode)
    • Each player uses a deck of 60 cards
    • Initial health is 30 points
    • Draw 5 cards in the first round, and 1 card each round thereafter
  • Game goal : Reduce the opponent's health to 0, or meet special victory conditions
  • Core gameplay loop : draw cards → acquire resources → use cards → perform strategic actions → end turn
  • Key mechanism description :
    • Fusion system : Ancient cards and modern cards can be combined to create new effects
    • Collaborative action : In team mode, teammates can share specific resources and card effects
    • Era conversion : Under certain conditions, the "era status" on the field can be changed, affecting the effects of all cards
  1. 4.  Card system
  • Card Types :
    • Source Card : Relics and technologies of ancient civilizations (provides basic abilities)
    • Technology Card : Achievements of modern science and technology (provides variability)
    • Fusion Card : A completed fusion of the past and the present (powerful but rare)
    • Character Cards : Characters with special abilities
    • Event Card : A special event with a one-time effect
    • Field Card : A persistent effect that changes the battlefield environment
  • Card attributes :
    • Civilization types : Atlantis, Maya, Babylon, Mu
    • Technology fields : quantum, biological, mechanical, electronic
    • Energy consumption : The amount of energy required to use a card
    • Fusion level : A value that reflects the degree of card fusion (affects the strength of the effect)
  • Rarity System :
    • Normal (white)
    • Excellent (green)
    • Rare (Blue)
    • Epic (Purple)
    • Legend (Gold)
  • How to obtain cards : basic card packs, expansion packs, achievement rewards, limited-time events
  1. 5.  Resource System
  • Resource Type :
    • Ancient Energy : Resources required to use the Source Card
    • Modern Energy : Resources required to use technology cards
    • Fusion points : used to activate fusion effects
  • Resource acquisition method :
    • Automatically gain a certain amount of basic energy each round
    • Certain cards can generate additional resources
    • Resources can be converted between ancient energy and modern energy, but there is loss.
  • Resource usage rules :
    • Unused resources are partially retained at the end of the round (up to 3 points)
    • Fusion points need to be obtained through specific card effects and are not obtained automatically.
  • Resource balancing considerations :
    • Focusing on a single type of energy can gain efficiency advantages
    • Balanced use of both energies allows for more combination possibilities
  1. 6.  Combat System
  • Battle process :
  1. Playing Cards: Using Hand Cards
  2. Fusion phase: card fusion
  3. Combat Phase: Declare Attack and Defense
  4. Effect Resolution Phase: Processes all activated effects
  • Attack and defense mechanisms :
    • Character cards can attack opponents or their character cards
    • Defense requires an unexhausted character card or a defense card
    • Some source cards and technology cards can be attached to character cards to enhance attributes
  • Special effects processing :
    • Fusion effects take precedence over normal effects
    • Instant effects can be used at any time
    • Chain effects are settled in reverse order of triggering order
  • Damage calculation method :
    • Base damage equals attack power minus defense power
    • Special effects can modify the way damage is calculated
    • Cards in fusion state have additional damage effect
    1. 5.  Game flow
    • Game Preparation :
      • Players prepare a deck of 60 cards
      • Randomly decide first move
      • Draw your initial hand (optionally replace once)
    • Round Structure :
    1. Start phase: trigger the "turn start" effect and obtain resources
    2. Draw phase: draw a card from the deck
    3. Main stage: Use cards and fuse them
    4. Combat Phase: Declare Attack, Resolve Combat
    5. Ending phase: trigger "end of turn" effect, settle the lasting effect
  • Stage Description :
    • Any type of cards and abilities can be used in the main phase
    • Only combat-related instant cards can be used during the combat phase
    • Each stage has a corresponding special timing card
  • Special occasions :
    • Era Transformation: Some powerful cards can change the era status on the field
    • Crisis Event: Randomly triggered full-game effect that affects all players
    1. 6.  Victory Conditions
    • Main ways to win :
      • Reduce the opponent's health to 0
      • Prevents the opponent from drawing cards (deck runs out)
    • Alternative victory conditions :
      • Collect and activate the "core source devices" of four civilizations
      • Achieve "Perfect Fusion" (having more than 10 fusion levels on the field at the same time)
      • In team mode, eliminate any player on the opposing team
    • Draw Processing :
      • When both victory conditions are met, the one who meets them first wins.
      • If all players fail at the same time, it is considered a draw.
      • After more than 40 rounds, the one with the highest health value wins
    1. 7.  Scalability
    • Future expansion directions :
      • New civilization types (such as lost civilizations other than Atlantis)
      • New fusion mechanism (third-order fusion, cross-team fusion)
      • Single player exploration mode (uncover the secrets of ancient civilizations)
    • Variable rule suggestions :
      • Limited Mode: Restrict access to specific civilizations or technology areas
      • Draft Mode: Build a deck from random cards
      • Ruins Exploration: Use pre-built decks to challenge specific scenarios
    • Game Mode Variants :
      • 2v2 team battle : two players share health points and can use special synergy skills
      • Free-for-all : 3-4 players fight each other freely, the last one standing wins
      • Relics Competition : Compete for special resource points that appear on the field, and win if you reach the specified points
      • Time and space racing : players compete to complete a specific fusion combination, the first to complete wins
