Castlevania: Symphony of the Night(PlayStation - 1997 - 18 games, not counting remakes)
Konami's other hard-hitting franchise. Instead of state-of-the-art visuals and storytelling, this one's bent on keeping traditional 2D games alive. Typical games focused on the Belmont clan's mission to destroy Dracula, but here you played as his son, Alucard, who's grown tired of his father's devious ways.
What it did for the franchise
Except for Simon's Quest, the other games in this series were completely straightforward - walk right, whip stuff, beat the boss, go on to the next level. No new weapons, no new armor, nothing that could move you off your linear path. Then came Rondo of Blood, which introduced alternate paths but still ferried you along a fairly simple course. Its direct sequel, Symphony, gave players a massive castle to investigate, with no levels or pre-set path to follow. RPG elements like experience points, customizable weapons and armor, an updating map and even an item shop were at Alucard's disposal, making him the most formidable opponent Drac had ever faced. From this point on, every subsequent game in the series has followed this pattern, usually to critical acclaim and major fan appreciation. The series has reportedly sold around 20 million copies worldwide, and chances are a good chunk of that is all thanks to Symphony's change in gameplay. Fans have come to call it Metroidvania.
Who it inspired
Seeing as Castlevania is almost single-handedly upholding the values of 2D gaming (nods to Odin Sphere though), not many games are copying the brilliant ideas at work here. Still, the now-diluted Mega Man franchise copied a bit here and there for its Zero and ZX branches, and the forgotten Shaman King: Master of Spirits could have been the reason Konami opted to infuse Dawn of Sorrow with an anime look instead of the traditional Kojima paintings. The kiddies were gaga over the show, and the game was a third-rate ripoff, so why not make the real deal appeal to the same audience?
