Note: this is from a (longer) anime/game video review, look for links on my profile page.

Some were critical of Devil Kings due to the name changes, but it seems more deficient to have barely any narrative at all, just some one-liners that characters are programmed with, and despite being able to play everyone available in all the different domains, they barely make much difference in terms of changes to the script. This situation was improved somewhat in future games, but there is still a noticeable aspect of shallowness, and even when major characters go against each other, e.g. Ieyasu and Ishida, their programming only allows them a few novel lines, the rest being in common with the remaining characters.
