Going to have to disagree here. SOTN has amazing soundtrack, and the old ps1 version has the best voice overs and lines ever (outside of another 2d vampire games blood omen, but I digress).
The 2d graphics with paralax scrolling was amazing on SOTN, and was unmatched with any gba or ds games. Not until dracula X chronicles (rondo's 2.5 remake on psp) did we get better 2d style graphics.
Aria limits the amount of gear and equipment compared to SOTN, as it's a smaller game.
Also I didn't dig Aria's starting setting or the anime characters/artstyle.
SOTN felt castlevania. It didn't take place in 2035 Japan with a high school student. Aria feels like more like Castlevania SOTN lite.
SOTN took place in the proper 1600s/1700s setting in Transylvania area.
Continuing the CV linage from CV1, 2,3, 4, and Rondo. It oozes Bram Stoker and Dracula lore.
Not saying Aria was bad, it was a good game for the platform it was on, same with Portrait of ruin, harmony of dissonance, circle of the moon and dawn of sorrow.
Now i will say I straight up didn't like Order of Eccelsia... that game had great artwork but shit gameplay. I wanted SOTN not 2d dark souls (without the souls part).
