DmC: Devil May Cry may have been an interesting game on its own but many Devil May Cry fans distanced themselves from it as the redesigned Dante didn't leave a good impression. It turns out the game almost caused Hideaki Itsuno to resign.
Devil May Cry was successful ever since the first title in the series but it wasn't until Devil May Cry 3 that it became a hard hitter franchise for Capcom. The original director, Hideki Kamiya, left after the first title and Hideaki Itsuno took over the role of director in the last five months of Devil May Cry 2 development.
The man then continued to build on the success with Devil May Cry 3 and 4 but the tale almost took a turn for the worse after Itsuno apparently wanted to resign following the not-so-beloved DmC: Devil May Cry. According to Reuben Langdon, who voiced Dante in all instalments fully directed by Itsuno, the director wanted to leave Capcom after DmC: Devil May Cry.
In Langdon's words, Itsuno didn't like the change of direction and was ready to resign but Capcom weren't keen on letting him go just like that. They apparently recognised his value and decided to give Itsuno whatever he wished to stay on the team.
One of those wishes was to gain full control of Devil May Cry for another game, as he was only a supervising director for DmC, and Capcom obliged, resulting in Capcom fulfilling his wishes. Langdon proceeded to commend both Itsuno for standing up for the series and Capcom "for going all out" to make him stay.
The result was, as you are probably well aware by now, Devil May Cry 5 which returned to the series roots with the normal Dante, the newcomer Nero and some other fan favourites such as Lady, Trish and a certain boss that will remain unnamed here due to potential spoilers.
