Aria of sorrow is on my opinion the best castlevania game for the gba, the soul system is a very interesting thing, full souls soma + chaos ring is basically a walking debug mode with certain limitations. This is a good castlevania for someone who wants to start on this saga because it is a good, not that easy but not that difficult either castlevania. The story is decent, not bad not good it is just there, what is interesting is the implications on who soma actually is, and his redemption or second chance in life, and the burden lifted on arikado's soul, sort of speak
