Castlevania Series

[Ultimecia]

Symphony of the Night (PS1, Saturn) is the best IMO, followed by CV3 (NES). The GBA and DS titles are very good too, the only not so great was Harmony of Dissonance. But all NES games are pretty good. The DS one lost some of the "touch" the old games had, becoming more "anime-like" and "kids-friendly" (in visual identity terms)

The N64 and the PS2 games are horrible, only Legacy of Darkness (N64) is so-so.
