For the most part, it's another fantastic entry to the series. Moreover, it's a great game to re-introduce old fans of the series with its graphical and mechanical upgrades. If Pokemon X or Y interests you, consider picking it up; unless you're completely turned off of the franchise, you'll find much to enjoy in this 3DS game.
Conception II is an unusual beast. On one hand, the game could have used a lot more creativity when it came to the dungeons themselves, the throwaway plot is discouraging, and it doesn't do any one thing exceptionally brilliant in the gameplay department. On the other, the game looks incredible, the music is fantastic, and the combat system can be intense when the difficulty goes up. For fans of the genre, this is definitely one worth picking up, but for those on the sidelines, it may be an easier purchase later on.
