Many, many choices are available for this list, but out of them, I have chosen After Burner II. It was one of the first PC Engine/TurboGrafx-16 that I have been exposed to through
SuperPCEngineGrafx's site, and I was mindblown by the sound that was put out, even so I wanted to listen to the first song (which was all I've listened to in order to avoid spoiling myself in case of meeting the game in real exposure) over and over again. It still remains one of the most glorious ones to listen to even now, even with many others heard, and through videos of its gameplay, it looks to be of an incredibly fun game.
There are many notable choices from this list, as well, such as Bomberman and Super Star Soldier. However, I did not find any of them to be as hard-hitting as that game.
