Like the name suggests. Name a great hidden gem that people may not know about.

For me it is a series. The series is the Romance of the Three Kingdoms.

It is a stageity game that takes you back to China 180AD. The Han Empire is in its final days and warlords look to seize control of the land to become Emporor themselves. Control Hero's and villians from the time. Recruit an army, steal other war lords best generals, and take control of the land. This series is addicting, and depending on which one you plug in it changes quite a bit. It is worth a try if you have never tried it yet.
