Why Game Developers Should Aim for “Good Enough” Security, Not Unhackable

Summary

A game-security explainer argues that developers cannot fully control player-owned devices, so they should prioritize high-impact risks, move trusted decisions to servers, raise attack costs, and deliberately accept, mitigate, transfer, or avoid residual risk.

Key points

• Because players own their devices, they can inspect files, change memory, and replay traffic; client-side checks can deter casual cheating but cannot provide perfect protection.
• Prioritize risks by impact, not how alarming they sound: offline cheats may affect only one player, while multiplayer cheats can undermine fairness and revenue.
• Keep authoritative decisions about rewards, inventory, match results, and purchases on systems the developer controls, rather than trusting the client.
• Economic protection aims to make cheap, casual attacks costly enough that they are no longer worthwhile.
• Choose how to handle residual risk: accept, mitigate, transfer, or avoid it; reassess when a game's features or value change.
