Tango was hardly a "husk" just because Mikami left. Going purely by his credits, he had very little creative involvement in any of the studio's output beyond their first game. It's important to remember that games are made by a ton of ridiculously talented people whose names most people never learn or even see. Tango was probably at the actual height of their game and poised to jump into even more prestige after Hi-Fi Rush, which is what makes this shuttering so tragic.
Let the voice of love take you higher,
With this gathering power, go beyond even time!
