Those are really good reviews! Ninja Gaiden is one of my favorite games, and although I never really got into Castlevania 1 that much, I do like Castlevania 3 a lot (just need to finish it, some day.) The only two things I can think of that I feel differently about are:

#1: I liked the sequels to Ninja Gaiden, and I may even like NG2 a little more than NG1, because I thought it had some more inventive obstacles, like the wind in that one level, icy floors, the fire level, and the lightning that lights up the otherwise dark screen. Some of the boss fights were better, too, as they didn't just involve standing in front of the enemy and button-mashing with your sword to win. But I'm one of the few people I know who actually likes NG3.

#2: Castlevania has a boring plot? I think the idea of the Belmont clan fighting Dracula who revives, along with his ancient evil castle every 100 years is cool! And CV1 was the first in the series, so it's not like that plot had been done a million times, yet.

But, bravo! Those were really good reviews, and I enjoyed reading them! You're very good with descriptions and you made me want to play those games again! =)
