Name a game that is excellent that many don't know about.

Have you ever heard about the game "Summer Carnival '92: Recca" for the Famicom?
Probably not, since it was originally only released in Japan.
Anyway, this game is super-intense for an 8-bit game, there are enemies everywhere and even the first stage is a major test of your reflexes.
Here is a video demonstration of the gameplay in this game - prepared to be overwhelmed:



Also, just to make sense of the name:
"Summer Carnival '92" refers to a gaming competition that was held in 1992, and "Recca" is the Japanese word for "conflagration" or "raging fire", which sums up this whole game pretty well.
