The Blueprint for Modular Game Systems What is Packs v1? Packs v1 is a foundational architecture for modular, collectible, or loadout-based game mechanics. Unlike a simple “inventory bag,” Packs v1 treats each pack as a self-contained system with its own rules, capacity, synergies, and upgrade paths. It is designed for games where players assemble, upgrade, and deploy sets of items, abilities, or units—think card decks, gear sets, ability loadouts, or even creature teams.
