WWE WrestleMania 21 (2005) was released exclusively for Xbox, aiming to deliver a cinematic WWE experience. Featuring detailed graphics, voiceovers, and a storyline-driven career mode, it attempted to capture the spectacle of WrestleMania. The roster included top WWE stars, with entrances and arenas recreated in detail.

Gameplay, however, was criticized for sluggish controls and bugs, holding it back from greatness. Despite this, its ambition and presentation stood out, making it a notable entry in WWE’s Xbox history. It is remembered as a mixed but bold experiment during the Ruthless Aggression era.
