I'm hearing mixed things about If My Heart Had Wings' editing. Some people are saying that the loss of H-content made little to no difference in the storylines and others are saying it did.
It's like, in Mugen Souls the omitted bath house scenes made no difference. If Agarest War 2 omitted the oil massage scenes, it would make no difference since those felt like a tacked-on afterthought.
On the other hand, I didn't know till after the fact that Tea Society of a Witch was originally an H-game and its English release had THREE characters' storyline branches omitted.
ASIDE: Although Crescendo's good endings are beautifully written, I actually felt that the non-H endings were often more powerful. That being said, that game would be an absolute mess if it was ever edited.
