A developer who previously worked for Retro Studios on Metroid Prime 3: Corruption has accused Nintendo of "micromanaging" the project. The artist, Nate Purkeypile, didn't deny that the game turned out great in the end, but he did have a fair amount of criticism to share regarding Nintendo's working relationship with the studio and its employees. The claims are all the more poignant in light of the ongoing work on the long-delayed sequel from Retro Studios, Metroid Prime 4: Beyond.
