On the other hand, if people keep asking about it, then maybe the listings aren't as clear as they could be. It might not hurt to put "(A New Translation)" or "(movies only)" or something after the mecha name.
I think perhaps it might be more people just ignoring obvious pieces of information, such as the section name and format. But since the damn question won't go away, I might have to do that.
EDIT: To end this once and for all, I went and added "(movies only)" for Zeta, as well as MSG for the Core Booster. Also went ahead and did the same for SEED and DESTINY, since the Special Edition additions have also been questioned in the past.
