Even at full price, a PC/PS5/XBSX collection of the Ninja Gaiden games is guaranteed to sell well.
Ideally, it would contain the NES trilogy, every version of the Itagaki era reboot trilogy, and Yaiba: Ninja Gaiden Z (for completion purposes).
More realistically, it would just be the Itagaki trilogy, each the "best" version.
I fear that this series is going to be lost to time if there isn't a collection/remaster at some point, and that would just be sad.
