Another notable early example of the genre was Kure Software Koubou's 1988 PC-8801 strategy RPG, "Silver Ghost", which was cited by Camelot Software Planning's Hiroyuki Takahashi as inspiration for the "Shining" series of tactical RPGs. According to Takahashi, "Silver Ghost" was "a simulation action type of game where you had to direct, oversee and command multiple characters." Unlike later tactical RPGs, however, "Silver Ghost" was not turn-based, but instead used real-time strategy and action role-playing game elements. It also featured a point-and-click interface, to control the characters using a cursor. A similar game released by Kure Software Koubo that same year was "First Queen", a unique hybrid between a real-time strategy, action RPG, and strategy RPG. Like an RPG, the player can explore the world, purchase items, and level up, and like a strategy video game, it focuses on recruiting soldiers and fighting against large armies rather than small parties. The game's "Gochyakyara" ("Multiple Characters") system let the player control one character at a time while the others are controlled by computer AI that follow the leader, and where battles are large-scale with characters sometimes filling an entire screen. "Master of Monsters", developed by SystemSoft and released in 1989 for the "MSX2", added fantasy characters and magic attacks to the gameplay of the wartime combat "Daisenryaku" series, which had instead opted for tanks, planes, and other vehicles of real-world modern combat. "Master of Monsters" also added experience bars for the character units, a concept which would be adapted and popularized by later console-based series like "Fire Emblem". Unlike many other early titles in the genre, "Master of Monsters" made its way to the west via a port to the Sega Genesis in 1991, albeit only in North America.
