At the risk of a tangent, Onimusha 2 was the best of the series. It felt like a true chambara title, mixed with anime character designs. It also has the most replay value, since you can align with different characters.
The opening's awesome! What's not to like about Nobunaga razing an innocent village to the ground with zombie warriors, and (like you say) those fantastic intro shots!
No way, Jose. They ruined it with the time-travel nonsense, and absence of Jean Reno's voice.
Prepare for some disappointment.
Ew. I hated O2, comparatively speaking. It's like DMC2 - not bad on its own, but as part of the series, it's not very good. The other character's side stories were interesting, sure, but they were still annoying as hell. And the trade system was stupid - all that work just to get those three bone keys for the end of the game, a few healing items, and to manipulate your scenes. However, the scenes were a cool idea. I like how it would sometimes affect how the game was played - like when you'd switch gameplay (the Oyu part was the best, period; Magoichi's wasn't much fun, though Kotaro and Ekei's wasn't bad). I liked the Magoichi bit during the Gingamphatts fight, though. BOOM
The opening, though, is cool, but a tad generic. There's no shortage of village razing openings. The Nobunaga part's still kickass, though. I don't like the art for the characters themselves in the intros, though. They positively suck (and you know you can't defend Kotaro or Magoichi, no matter HOW much you try xD).
MADNESS. O3 was easily the best. The time travel part was kinda funky, but Jean Reno's very presence is all that was required, really. His voice WOULD have been bad-fucking-ass, though. And, tbh, I liked his in-game character more than Samanosuke, really. Playing with the whip was way more fun.
Yeah, I found it again...it is a bit of a disappointment. Though even from the beginning it's very clear that Tenkai is
- and I haven't even finished the game yet!
The first game had a really good opener, though - shot through the throat, Samanosuke doing the fighting, etc.
