I honestly liked PoR more than Rondo, to be honest. Rondo these days is overly-hyped. When there are lots of bad things about the game.
-Stage 5'
-Badly animated cutscenes, but that's more of the system's problem
-Ugly backgrounds. Like, really ugly in a lot of cases.
-Backflip. Not the move itself, the way to perform it. There were plenty of other ways it could have been implemented, especially in the DXX version.
That's only some of the many things. Whereas PoR is bashed constantly, but there's a lot of cool things in the game.
And if you ask me, DXC fixed a lot of the problems with RoB. Stage 5' was completely redone. The animated cutscenes were replaced with dialog scenes in the style of Symphony (except they looked cooler in this game). The backgrounds looked much nicer, but it's a little unfair to compare a PSP in 2007 to the PC-Engine in 1992.
Oh, and the voice acting was much better. If by wooden, you mean no real emotion and practically monotone, you are completely wrong. Not charming, you are wrong. Forgettable, wrong. Well, in any case, it's the complete opposite to me.
NOT WOODEN: See the Annette battle as Richter. He realizes he has to kill her. He feels sad, and you can tell. He knows what he has to do, and then kills her. What makes it sadder? Annette screams out Richter's name upon death.
CHARMING: Alucard and Dracula don't sound like gruff beast and typical villain respectively. While Dracula may sound it in some ways, let's face it. This voice matches the regal villain of this series way more than his original voice. Richter sounds really awesome, and not like your typical PSX[ hero (serious, that guy's voice was in like EVERY PSX game).
