You know, the scores so far have been pretty good in my opinion. I expected lower scores from IGN and Gamespot, they seem to have it out for any game that I absolutely love and dig for superficial reasons to downrate it. I hardly ever visit their site or listen to the reviews. As Thernz pointed out, clearly some SOTN fanboyism going on there. Which is all well and good, SOTN was and still is a great masterpiece of a game. But just because this isn't exactly like a Metroidvania doesn't mean it should be downrated or ignored.
Some opinions will always differ from person to person and some negative points I've seen pointed out actually are positive ones for me personally. All in all, despite the lukewarm to great scores, LOS is going to rock my socks off. And I'm hoping people will worry less about meaningless numbers and more about their personal experience with the game. Since this of all incarnations deserves to be played and enjoyed by everyone, not just Castlevania fans.
