The loading times in the Saturn version (aside from maybe the boss loading times) aren't LONGER; they're just handled differently. The CD rooms in the Saturn version don't even trigger the loading sequences until AFTER you reach the very end of them.
That's the whole point of the CD rooms: as you walked through them in SotN, the game WAS loading so that you didn't have to wait for it when you reached the end of it. In NitM Saturn, you have to wait for the loading even after using your time to walk through the room.
And, yes, you do have to go into the menu to view the map each time: another messy delay, and yet another hidden load time is present when you attempt to go back to the game from it.
There's also extra slow-down when too many enemies are present, and some areas have staggered loading within themselves, like they have to load a new section.
NONE OF THIS was present in SotN. You could say neither were the additions of the other things like music and playable Maria, but what I'm saying is SotN never needed them (except Maria). They just feel out of place, unbalanced and unnatural. Even the new music.
Maria's great: she's a power goddess with a fucking triple jump, but it's her assets that devalue the purpose of the secondary quests in the first place, which were to give a more classic CV run for the same castle. But her game turns out to be a challengeless, and thus uninteresting 10-minute frolic of completely owning everything onscreen. She's so deadly that's it IS fun just to witness all the destruction and the various ways she deals it... for awhile. But when you realize that's it's nothing but an unstoppable linear romp from one room to the next with no obstacles or satisfaction from accomplishing any goals... well you tend to feel unsatisfied.
It's like equipping Soma with the Panther, Bat and and fireball souls (I don't remember the real name of the fireball one) -- YEAH it's a blast to tear through areas near the end of the game, and it's a much quicker way to get around, but would you feel satisfied playing a whole game of that? I don't think so.
Maria can triple-jump over everything -- every attack, projectile and platform. She can also wholly defend any incoming damage and she can deal a flurry of punches and kicks from a safe distance.
If you thought RICHTER'S game was shallow, imagine raping that of any challenge whatsoever, but with the same featureless, storyless, streamlined castle.
Yay.
