I have to say, I was extremely unimpressed with Order of Ecclesia. I was happy for the return to a more traditional Castlevania art-style, but everything else about the game was just insanely boring. I also stopped playing once Dracula's castle - which, while not as large as previous iterations, was still no small map - made it's eventual appearence, and at that point I was kind of ready for the game to just be over. Then there was so much more.
To be perfectly fair, Harmony of Dissonance also lost my interests quickly. I did enjoy Circle of the Moon, after all, it was the reason I got a GBA, but Aria of Sorrow was just fantastic. By Order of Ecclesia, I was tired of Metroidvania titles. Now, after Mirror of Fate, I long to see another one. It's sad when one game can be so terrible it makes you want to be bored again.
