Dracula X and Donkey Kong Country Returns both down now, meaning I'm free to move on to Harmony of Dissonance.
Donkey Kong Country Returns may be a bit better than I remember, maybe not, and I'm honestly not entirely sure if those extra thirty frames per second helped significantly seeing as it's been a long time since I've beaten the game. The bosses certainly didn't get better though, with most sporting at least one bullshit maneuver that's impossible to predict, and incorporate too much RNG for my liking; fortunately Tropical Freeze vastly improved on the bosses. And it was still a bit rough around the edges in points where it didn't seem to flow as well as it could have, but otherwise, solid game, and as it stands, I think my ranking of the DKC series goes like this: Donkey Kong Country > Tropical Freeze > Diddy's Kong Quest > Returns > Dixie Kong's Double Trouble.
Dracula X is the hardest Castlevania I've played so far, and my least-favorite probably. SomecallmeJohnny hit the nail right on the head when he said that this game feels like it was designed for Castlevania IV's Simon but they decided to use the stiff controls of the previous games instead. Not only that, but invincibilty frames are noticeably fewer, causing you to take even more damage than you would normally. If this game had Castlevania IV's controls, it'd be fantastic, but with the stiff controls forcing artificial difficulty on you yet again, the Classicvania games aside from IV are becoming less and less my thing. I still plan on giving Rondo of Blood a shot, since good things are said about that one (and good things generally are not said about Dracula X), and I suppose 3's worth a try sometime, but it seems my heart belongs to the Metroidvanias.
