As far as Judgement, I think you almost have to be a Castlevania fan to like it, or to excuse it even. At least it doesn't appeal to hardcore fighting gamers. I really think it was a bad move as it tarnishes the image of the series. I played it and enjoyed it for about five minutes, but it is of pretty low quality IMO.
A spinoff fighter, that is completely non-canon (save for possibly Aeon) has tarnished the series image.
wut?
For starters, it isn't all that bad. Practically everyone I know who went in with horrible expectations said that it way exceeded their expectations. Some reviewers are hailing it, others are smashing it (in frankly embarassing reviews, go read 1ups, its good for a laugh). Some reviewers, professional reviewers, are saying its gameplay mechanics are deeper than Brawls, but the game itself needs work. I agree.
The game has all the potential for a fantastic fighter. The mechanics are there, the stages show potential, but all thats missing is time. As usual, the game was rushed, and its obvious when you play through story and castle mode, and not even 8ing can make a deep fighter on a short schedule.
And it was never meant to be a hardcore title, if anything, it was built for casual fighting fans, its a great pick up and play game.
