Hell look around youtube or gametrailers for the teaser for Lords of Shadow and the very first comments are
"This should be a Castlevania."
"This would have made a great 3D Castlevania game"
"Might as well be called Castlevania Lords of Shadow."
"If Simon, Richter,Kratos had a baby."
"Konami making a Castlevania rippoff?" lol
"Game looks like it might be using the Metal Gear Solid 4 engine, I wonder if Hideo Kojima involved with this game?"
That's why it shocked me that even when people saw this game the first time and thought it looked like Castlevania, and then a year later the game turns out to be a Castlevania and people turn around and say "This game doesn't look like Castlevania. They just slapped the Castlevania name on a game that looked exactly like a Castlevania game."
