I would say that the Metroidvanias are on the same technical level of Legend of Mana. It's kinda hard for me to imagine how Castlevana would look without sprite reuse, because I was never really fond of the paper cut out rotation techniques used in Oboro or Odin Sphere or Shank. I mean, in the first two, they fit the style, but I can't see them working in Castlevania with its emphasis on realism, well, stylistically. Also, for some reason, I honestly prefer SoTN. It might just be all the intriacries and composition. It just strikes me as bolder and richer, despite technological inferiority. Well, when it comes to 2D, it's always better to have something hand-pixeled than use a technological gimmick like rotating, shifting, or morphing. It's much more natural.
i-im not arguing against new graphics. im just saying if they finally do get into gear, i hope they dont rely on what the newer 2D games do, but does its own thing with hand crafted precision.
With PoR, I just found it to be an exercise in grinding and excess. The gameplay with its hp tank bosses, leveling up subweapons, fetch quests, and etc. It's pretty much the game that sums up what drags down the Metroidvanias for me. That's why I don't like DoS or PoR. I mean, OoE shares those problems too with the bosses and quests, but then it strips down the inventory and revamps the combat to make it the fastest it's ever been and I am swooned. Probably one of the few Metroidvanias that actually invested in the potential of its gimmick. Too bad its level design was pretty horrid at times and despite all the new assets, it still manages to have the worst cohesiveness in graphics use. shanoa-baby ; - ;
