No—RuneScape has never received an official PlayStation 3 release. The MMORPG has remained exclusive to specific platforms throughout its 20+ year history.
Jagex, the developer, has historically focused on platforms with keyboard/mouse or touchscreen input—essential for RuneScape's complex interface. Console controllers struggle with the game's extensive menu navigation, skill interfaces, and chat systems. Additionally, Sony's certification requirements and revenue sharing for persistent online worlds presented business hurdles.
There are no announced plans for PS3, PS4, PS5, or Nintendo Switch versions. The mobile clients remain the most accessible way to play on non-PC devices, offering the complete game experience with touch-optimized controls.
