'Castlevania Aria of Sorrow' proves to be the best Game Boy Advance entry

"Aria" added an ingenious new mechanic that took advantage of the series' diverse cast of monsters -- the soul set system. When players vanquished a beast, they'd have the chance to collect their soul which would grant new abilities and open up new areas. It made for the best GBA entry by pushing the limits of the hardware and delivering an intriguing plot twist. It comes close, but just barely misses the number one spot.
