Simon's Quest is still my favorite. It was the first I played, the first I finished. Then I went back and finished the first and when the 3rd came out I got stuck on that but it was a rental and I didn't like it that much compared to the others. I guess Simon's Quest tainted it for me because I never really liked the other ones as much. Super Castlevania IV was better but it wasn't until SotN that it felt like Simon's Quest again.
So anyway, I bought this awhile back and I still don't think I've unlocked SotN. This plays more like the original, which in my book isn't a good thing, especially with all the GBA versions like Simon's Quest. This reminds me a lot of Harmony of Dissonance which I hated.
