Introduction

SGC, or SG Coin, is the on-chain utility token that powers KAI SANGOKUSHI TAISEN — Battle of Three Kingdoms, a Web3 tactical card battle game. The project bridges SEGA's beloved arcade franchise with blockchain technology, bringing NFT ownership, staking mechanics, and a player-driven economy to a competitive strategy game.

Unlike many GameFi tokens, SGC is designed around a 'Gamer First' philosophy — the core game is fully playable without owning any tokens, ensuring that skill and strategy remain the primary drivers of progression.

History & Background

The game was developed by double jump.tokyo, a studio founded in 2018 with a track record of titles like My Crypto Heroes and Brave Frontier Heroes, and partnerships with publishers including SEGA, Square Enix, Bandai Namco, and Ubisoft. The studio received $35 million in funding from institutions such as Amber Group and Jump Crypto.

Leading the project is Yasuhiro Nishiyama, the original creator of SEGA's Sangokushi Taisen. The team built SG Verse — a gaming-focused Layer-2 blockchain on Oasys — in partnership with AltLayer, tailored specifically for gasless, high-performance gameplay.

How SGC Works

SGC operates within a dual-token economy. Players earn SGCP (SG Coin Points) by competing in tournaments, climbing the monthly PvP leaderboard, and participating in campaigns. These points can then be converted into SGC, the on-chain token.

The game features a dual-card system: standard Warlord Cards and Awakened Warlord Cards, which are minted as NFTs. Awakened Warlords carry unique 'Awakened Skills' that provide tactical advantages, and duplicate NFT copies can be burned to level up generals, creating an organic deflationary mechanic.

All match outcomes and card drop rates are recorded on-chain to guarantee verifiable fairness.

Tokenomics

SGC functions as the primary value layer of the KAI ecosystem. It is used to purchase card packs (Orbs), enter exclusive tournaments, and unlock advanced in-game features. Staking SGC rewards participants with in-game points, creating a feedback loop between competitive play and token utility.

The token distribution includes allocations for marketing campaigns and community engagement alongside the broader ecosystem development goals.

Ecosystem & Use Cases

• Card Pack Purchases: SGC is spent to acquire Orbs containing Warlord Cards.
• Tournament Entry: SGC unlocks access to competitive ranked events and guild battles.
• NFT Marketplace: Awakened Warlord NFTs can be traded, upgraded, or burned using the ecosystem's marketplace infrastructure.
• Staking: Holders can stake SGC to earn in-game points, incentivizing long-term participation.

Team, Governance & Community

double jump.tokyo leads development, with Yasuhiro Nishiyama — the original Sangokushi Taisen creator — at the helm. The studio's deep roots in both traditional game design and blockchain infrastructure give the project strong technical credibility.

The community communicates through official channels including Twitter (@b3k_games) and Telegram (KAIB3KAnnounce). Future roadmap items include DAO integration and deeper governance tools, which will give token holders a role in shaping the game's direction.

Advantages

• Strong IP backing from SEGA's Sangokushi Taisen franchise with an official license.
• Experienced developer — double jump.tokyo has shipped multiple blockchain games with major publisher partnerships.
• Skill-first design keeps gameplay quality central, reducing dependency on token spending.
• On-chain transparency for all battle outcomes and drop rates builds player trust.
• Multi-platform availability on PC, Android, and iOS broadens the potential player base.

Risks & Challenges

• GameFi sustainability — maintaining a healthy token economy long-term is a persistent challenge across the sector.
• Market competition — the blockchain gaming space is crowded and player retention is difficult to sustain.
• Token-game balance — separating token incentives from core gameplay is complex and requires careful ongoing calibration.
• Regulatory uncertainty around NFTs and GameFi tokens remains a global concern.

Long-Term Vision

KAI Battle of Three Kingdoms aims to demonstrate that blockchain gaming can prioritize genuine entertainment without sacrificing economic incentives. By combining a globally recognized IP, a performance-optimized Layer-2 chain, and a player-first token design, the project aspires to become a benchmark for sustainable GameFi. Planned expansions include DAO governance, deeper guild mechanics, and continued refinement of the NFT economy to reward long-term community engagement.
