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?
Metal Gear Rising: Revengance. Also always found Simcity 3000 real funny because they just kept going with the numerical order established by Simcity 2000, without the relevant millennium being anything to do with the game or near the release date
