Oh yeah.. I remember playing SOTN when it came out, and it still felt very much like castlevania to me... Is there anyone here who bought it and said "this doesn't feel like castlevania..."? Just curious....
It definitely felt different. What helped the crossover, for me, was the sprite re-usage from Dracula X, especially playing as Richter right off the bat. Once I got to Alucard, though, I started going "they really changed quite a bit, didn't they?" My character had a sword and a cape instead of a whip instead of a tunic and whip. The architecture was much more indoors, and much more regally Gothic, as opposed to the older, decaying medieval castles from the other games with their graveyards and brick walls. The areas that were dark were much darker, and the areas that were light were much lighter, as opposed to the overall muted feel of the previous games. The music playing wasn't Opposing Bloodlines and seemed like something you'd find in a ballroom (Alchemy Lab to be specific. Dance of Pales was also a new type of song choice for the series, going with the whole waltzy feel), the first level was inside during a thunderstorm with the lights off instead of outside in a village on fire, etc.
While it doesn't seem like it in retrospect, if you go back and compare Symphony of the Night to an older game (Dracula X in my case, being the game I played right before it) there are quite a few differences we gloss right over. I mean, the later levels in the Classicvania's were castle rooms, while in the Metroidvanias, we get these crazy alternate dimension stuff. Symphony of the Night really made the game focus on the Demon Castle. The castle seemed like a living thing. It had really weird, sometimes organic levels, the whole adventure taking place inside of it. This is as opposed to taking place before the castle, in the castle, around the castle grounds, and then back to the top of the castle, where the castle was just this dilapidated, monster infested castle. I mean compare the levels in CV IV and Dracula X to the levels in Symphony of the Night. If we take out the Nocturne in the Moonlight exclusives, SotN takes place ENTIRELY in indoor levels. CV IV and Dracula X had villages, farms, jungle like areas with rivers, etc.
That's not to say there aren't similarities. Like I sad, you've got the reused sprites, mainstay characters like Death, and anachronistic levels like clocktower. There's still Dracula, still Belmonts, still little things like candles and hearts (which were completely useless in SotN IMO. I never needed to use sub-weapons. That has nothing to do with what I'm talking about though), and still a castle. I mean, when it comes down to it, it was still Castlevania.
Didn't mean for the post to get this long, but hey, I could have actually talked about gameplay, which is like *woosh* whole 'nother 3 paragraphs.
