Progression Tree

A branching tree of upgrades you unlock over time — use it as a tech tree, a policy tree, a talent tree, or any path of growth. Each node has prerequisites, a cost, and an effect once unlocked. You don't get to free-click whatever you want: the world hands you progress as your actions earn it, then unlocks the nodes you've worked toward, and each one shapes the rest of your run. Great for strategy and nation-building worlds, RPG character growth, or a startup leveling up. Creators can rename it to fit the setting.
