Koei had some very humble roots in simulation and strategy games. Some of my all time favorite games of the SNES era were by Koei: Aerobiz Supersonic, Pacific Theater of Operations 2 and Romance of the Three Kingdoms IV: Wall of Fire. After not playing their games for a while, they blasted their way back into my life when Dynasty Warriors 2 was released on the PlayStation 2. Their somewhat surprising merge with Tecmo meant they no longer only concentrate on strategy/simulations games but they continue to release solid titles to this day.
