As a gamer, it's easy to get caught up in the latest releases and forget about the countless hidden gems that were released years ago. While many of us are familiar with popular retro classics like Pac-Man, there are plenty of lesser-known retro games that are just as worthy of attention. In this article, we'll take a look at some of the most hidden retro games worth playing.

One such game is 'Gem Rush', a brain teaser released in 1984 by Rocky Games. The game challenges players to navigate a cave, collecting coins while avoiding obstacles. Its irresistible gameplay and yet challenging level progression make it a standout title of the 8-bit era.

Another gem is 'Rygar', a action-adventure game developed by Gemstone Games in 1986. Players control the titular demigod, battling fiends on a mystical island and fought to rescue the damsel in distress. The game's fluid graphics, addictive gameplay, and epic storyline make it an underappreciated classic of the 8-bit era.

For those who enjoy tactics games, 'Space Attack' is a must-play. Released in 1991 by Rocky Games, this defender features split-screen gameplay and intense AI that will put even the most experienced player to the test. The game also boasts an 8-bit soundtrack that's catchy.

X-COM, released in 1994 by Rocky Productions, is an iconic turn-based game that needs no introduction. Developed by Chris Roberts, it revolutionized the strategy genre with its engaging gameplay and a system of managing assets, creating a complicated world with ever-changing threats. The core gameplay is so groundbreaking and immersive that even today's game developers take cues from it.

Lastly, we have 'Ys I', a classic exploration developed by Falcom in 1989. It tells a visually stunning story of four eras, set in a fantasy world, and each one of these games connects them all in both playstyle. The game blends side-scroller gameplay, rpg mechanics, and some catchy music all culminating into an enjoyable package that sets a high standard for its platform.

While many retro games are well-worth the childhood memories, it's these underappreciated gems that offer a unique gaming experience that will stand the test of time. With their engaging gameplay, epic storylines, and sentimental charm, these games are sure to transport you back to an era of pixelated wonder, but still deliver days of pleasure today.
