I remember as a kid hanging out in Arcades. Tetris, assorted fighting games like Tekken and Street Fighter, House of the Dead. So many great and classic titles. There was one I recall as well, Gradious. Gradious was a side scrolling shooter that wasn’t a bull hell (bullet hell was imported in years later to America); it was more like clear the screen and avoid the many obstacles in your path. Everything was near shoot able and the bosses filed the screen complete with flashing weak points.
