Reward the behavior you want — legibly and proportionately
GDC-L1-PROG-000301
Statement
Rewards teach. Players learn to do whatever the game rewards, so reward the behavior you actually want to see. Make each reward legible (the player understands what earned it) and proportionate (greater effort or skill earns greater payoff). Misaligned rewards train the fun out of the game.
02
Rationale
A reward is a signal that says "do more of that." If the most-rewarded action is boring, safe, or degenerate, players will gravitate to it and then blame the game for the tedium (the optimization pressure of SYS-0007). So the reward structure must point at the experience you want: reward bold play if you want bold play, exploration if you want exploration, mastery if you want mastery. Legibility matters because a reward the player can't attribute to an action can't reinforce that action — it reads as randomness (compare DESIGN-0006, legible consequences). Proportionality matters because rewards that don't scale with effort either trivialize achievement or feel unfair.
03
Applies when
Any system that grants progress, loot, currency, unlocks, or score — i.e. most progression and economy design.
04
Does not apply / Exceptions
Deliberate randomness has a place (varicrity and surprise; see PROG-0004), so "legible" means the player understands the rules of the reward, not that every drop is deterministic. And not every action needs a reward — over-rewarding trivial actions creates noise that drowns the signals that matter (compare FEEL-0004 on feedback). Some cosmetic or expressive rewards are intentionally disproportionate to effort and that's fine.
05
Implementation
Audit what your game actually rewards versus what you want it to encourage, and realign the gaps. Make the earning rule visible or discoverable. Scale payoff to effort/skill/risk so the exciting path is also the rewarding path (this is the incentive lever behind SYS-0007). Watch for accidental incentives — a reward attached to a boring-but-optimal action is a bug.
06
Disagreement
How tightly to couple reward to desired behavior is debated: tight coupling steers players cleanly but can feel manipulative or grindy; loose coupling preserves freedom but lets degenerate strategies flourish. Balances differ by genre and by how much the game trusts player-driven goals.
07
Notes
The constructive counterpart to SYS-0007 (players optimize the fun out): SYS-0007 warns of the failure, this says how to steer incentives so the fun path stays rewarding. Leads into PROG-0004 (intrinsic vs. extrinsic). Confidence 4.
