Konpeki no Kantai (Deep Blue Fleet) is a sophisticated naval simulation that serves as a fascinating relic of 1990s Japanese "alternate history" media. Based on the popular OVA and novels by Yoshio Aramaki, the game posits a scenario where Admiral Isoroku Yamamoto is transported back in time to change the course of World War II with advanced technology. Players take command of a technologically superior Japanese fleet, engaging in high-stakes maritime warfare across the Pacific. It is a dense, menu-driven experience that prioritizes historical (and counter-historical) accuracy over arcade action, demanding a significant investment of time and concentration.
The gameplay is split between strategic resource management and tactical grid-based combat. Navigating the myriad of Japanese menus is a daunting task for those without linguistic fluency, as the game requires meticulous planning regarding fleet formations, logistics, and fuel consumption. The tactical battles offer a satisfying depth, allowing for complex maneuvers with submarines, battleships, and aircraft carriers. While the pacing is admittedly slow, the satisfaction of outmaneuvering the Allied forces using superior "future" tech provides a unique hook that distinguishes it from more standard war simulators of the era.
Visually, the game is functional but uninspired, utilizing static portraits and map screens that evoke the aesthetic of early PC-98 titles rather than pushing the Super Famicom’s hardware. The orchestral soundtrack attempts to capture the epic scale of the source material, though it can become repetitive during long play sessions. Ultimately, Konpeki no Kantai is a specialized niche title that will alienate casual players but fascinate military historians and fans of the "Isekai" war subgenre. It remains a stark reminder of the massive library of Super Famicom titles that were deemed too culturally specific or text-heavy for a Western release.
