While its retro 2D graphics may have off-put some PlayStation gamers at first, anyone owning a 16-bit system can easily appreciate the greatness of Konami's Castlevania: Symphony of the Night. Konami took the side-scrolling idea to its fullest in this title. The game's enormous maps, huge range of weapons, constant enemies, and excellent balance all still puts this squarely on the all-time list, no questions asked. Add to that a memorable soundtrack and you have a gothic masterpiece that will serve as a benchmark for many future 2D action titles.
