Gameplay Systems

Manages the items a player carries — storage slots, stacking, weight limits, and equip/unequip logic — unlocking itemization, trading, and loadout building as a full gameplay layer.

A branching graph of unlockable abilities or upgrades a player spends points on, opening up build diversity and long-term character customization.

Tracks objectives, progress conditions, and rewards across potentially dozens of interlocking missions, turning exploration and combat into structured, goal-driven progression.

Presents branching conversations between characters, usually as a tree or graph, with localization and voice-acting pipelines in mind — unlocking narrative choice as a gameplay layer.

Combines gathered resources into new items or consumables via defined recipes, turning exploration and farming into a full production loop.

Tracks the production, consumption, and balancing of resources like gold, food, or mana over time, forming the economic backbone of strategy and simulation games.

Algorithmically builds levels, terrain, or items at runtime instead of hand-authoring them, unlocking near-infinite content and replayability.

Models a character or system as a fixed set of states and transitions — the simplest building block for giving NPCs distinct, readable behaviors like patrol, chase, and attack.

Lets NPCs navigate a level toward a target by combining a navigation mesh with a search algorithm, unlocking pursuit, patrol routes, and squad tactics.

A hierarchical model for NPC decision-making that composes simple tasks into complex, readable, and reusable behaviors — the standard for modern AAA enemy and companion AI.
