If You Liked the Collectable Aspect of Echoes of Wisdom, Try Castlevania: Aria of Sorrow
One of the more interesting facets of Echoes of Wisdom is how it’s basically a creature collector in disguise. Every time you defeat an enemy for the first time, you gain access to its Echo, opening up new strategies to tackle the game’s many obstacles. While Castlevania: Aria of Sorrow is not focused on gathering monsters to summon during combat, it does have a fairly similar take on collecting and using enemy abilities.
Most enemies in Aria of Sorrow have a special move that the protagonist Soma can gather and equip by defeating them. Unlike Echoes, it’s slightly more difficult to obtain these moves, since Konami’s title randomizes whether the slain monster will drop its ability, but the feeling it evokes is incredibly similar. You can spend hours combing Dracula’s Castle just to encounter every foe and add its powers to your toolbox.
As a Metroidvania, it’d also give you a bit of a break if you’re tired of the standard adventure fare after wrapping up Echoes. Best of all, the game is part of the Castlevania: Advance Collection, giving you two other fantastic titles for one reasonable price.
