Lords of Thunder
This game was made originally for the Turbo Duo. I'm glad Sega eventually ported it to the Sega CD, because it is a great game. You can choose from four different shooting styles, buy power-ups with the crystals you pick up along the way, and travel though many exotic locations. Although I like the music very much (it's heavy metal), it doesn't really fit with the "fantasy" theme of the game.
