We all know that there are essentially three kinds of CV games: classicvania, metroidvania, and 3D castlevania. The 3D variety haven't done well it seems. It seems the most enjoyed 3D games were CV64/LoD despite that graphics. They have everything that make classicvania great, but in a 3D environment. Now then, think of how amazing those games would look if they were given the graphics of now and given combos like in LoI (except not worthless). those games would be a lot better and more fun.
With all of that said, let's take those ideas and apply them to older games. For example, let's look at SCV4. Imagine that in a 3D environment (not side scrolling). It would be epic. Let's look at some of the unique parts of the game. Think of the rotating room of block 4-2 where u hang on to the whip ring while the room turns. Imagine how that would look in 3D. Let's also look at block 6-1 when u are jumping from chandelier to chandelier. It would add a nice challenge and would look awesome. Now on to block 9-1 and 9-2 (the treasury). Just the fact that you are going though Drac's treasury was already cool in 16-bit side-scrolling makes me think of the possibilities of doing it in a 3D environment. Last, but not least, let's look at block A-1 (the clock tower). There is one part where you are hanging from a whip ring that is carrying you over a large gap and there is an enemy waiting for you on the other side. That point is an interesting area and would be a great place for a QTE. Keep in mind that have some QTEs in a game isn't a bad idea (LoS overdid it/too many).
What do you all think? How awesome would it be if this was actually done?
