I won't go into detail into each one of the reviews.
However, there are some things I'd like to point out.
Why (WHY?) so low scores for all the GameBoy Castlevania games?
The fact that they are difficult doesn't mean they are bad.
If you lack the skills to beat them, just don't give it a low score based on that reason.
And Simon's Quest?
There's no reason to this. Simon's Quest is something unique. I agree with Dracula's Shadow, I made a post about that game once, it's brilliant, indeed, but Simon's Quest is also brilliant.
Why a score so poor for Circle of the Moon? And Dracula X for the SNES?
I know they are difficult, but you have to appreciate the quality. Circle of the Moon is a perfect way of mixing ClassicVania and MetroidVania, in my opinion.
And Dracula X for the SNES is very good in its own right. Of course you can't compare it to Rondo, that's logic because one is for PC-Engine, on a CD, and the other one for a 16-bits console, in a cartridge. And of course you can't compare it to SCVIV... which brings me to the final complain about your reviews.
WHY? I mean... WHYY??? you would give 1,5/5 to Super Castlevania IV?
The soundtrack featured some brilliant pieces of music, and though I love Yamane's style, there's no denying the high quality of SCVIV's OST, in terms of composition, arrangements, variety and atmosphere. And let's keep talking about the atmosphere. This game excels on that aspect. Every frame is designed with a heavy gothic and lonely feel, and that's why this game feels unique in the franchise. And the gameplay is just awesome. And talk about being objective... did you see the miracles this game make the SNES perform? Scaling, rotating rooms, interactive and moving backgrounds, 3D effect on the sky...
You may like it or not, but there's no valid point on stating that SCVIV is not brilliant.
A professional critic should know.
