Was The Elder Scrolls IV: Oblivion Canceled for PSP? Never Announced
Oblivion was never announced or planned for PSP. The only Elder Scrolls title on PSP is The Elder Scrolls: Blades (2019), a mobile port later brought to Switch.
Why a PSP Port Was Unlikely
Technical Limits: PSP couldn't handle Oblivion's open world without massive downgrades.
Focus on Consoles/PC: Bethesda prioritized Xbox 360 and PC.
Market: PSP was less dominant than Nintendo DS.
Bethesda may have considered it internally, but no official project existed.
