GEMFIRE (known in Japan as "Royal Blood")
It was an early-90s Koei strategy simulation game on the NES, SNES, DOS, and Sega Genesis. It was like Romance of the Three Kingdoms only in a completely fictional medieval fantasy setting.
Genesis version: Standard 16-bit fare for visuals and audio on the system. NO loading times!
SNES version: Slightly better graphics & sound, excessive loading times.
NES version: Inferior graphics & sound, excessive loading times.
DOS Version: Better than NES, worse than the others, and this is the original version.
There were sequels of it that never made it outside of Japan, I'd love to see a new installment for Windows or PS3. Would be a nice break from all the Romance of the Three Kingdoms games they keep churning out.
