The creators of God of War have already said that they were inspired by classics such as Castlevania, so it's a case of "give and take" in this industry, much like in anything else in the entertainment industry.
The final boss in Dawn of Sorrow was ENORMOUS, as was Galamoth, and Eligor.
Eligor in particular was kind of a "titan" because you had to climb him and take out different parts of his body. I think people are nitpicking now cause they're bored, and have to find something to complain about. Fans of Final Fantasy are exactly like this, bcause they have to wait so long for their games, and they would rather pay for FF7 over and over and over, than have the series evolve.
LoS looks amazing so far.
