- Flip-Flop of God: age has been notoriously inconsistent with the canonicity of the Altered Fable epilogue to Muv-Luv Alternative. While the story was clearly written as a follow-up to Alternative's ending, early releases had voiceover intros downplaying its relevance to Muv-Luv canon.

The matter was finally settled with the English release of photonmelodies which explicitly markets Altered Fable as an official sequel to Alternative.
