Why the combat feels slightly off:
-the animation is worse, both artistically and technically
-the sound design is worse, both artistically and technically
-the framerate (and possibly gameplay logic?) is no longer running in a locked and stable fashion, so even in areas where the average performance is better, everything feels less precise and reliable, including camera movement and item switching.
Honestly I regret buying the PS3 version, every area of this game has less a reliable feeling of control than even the worst sections of Dark Souls on the PS3. I'm expecting the better framerate of the PC version to improve things enough that I'll be able to rely on nimble play again instead of just memorizing everything and coming up with foolproof strategies, although artistically this game will still be just not quite comparable to the original.
