Names that really pique your interest or have some deeper meaning or just sound really cool.
For me, I like a lot of SMT/Persona titles, particularly - Nocturne's Japanese name, Lucifer's Call and the Persona 2 duology, Innocent Sin and Eternal Punishment.
Were there any games you liked in part because of their title?
Castlevania, Symphony of the Night
I'm pretty sure the "Symphony of the Night" part might be a line from one of the many Dracula books. But all my quick searches to verify just bring up Castlevania video game stuff instead of Bram Stoker's "Dracula".
OH!
I just remembered an old NES title called "Snake, Rattle, and Roll". Its a fun and puny title for a very hard but bright and upbeat game.
The Castlevania games with subtitles are always great. Nocturne in the Moonlight, Rondo of Blood, Aria of Sorrow
