Onimusha DOD is the best game in the series, and one of the best games EVER, it deserves to be HIGH UP on the Top List !
Onimusha DOD is for the PS2 exactly the same thing Dino Crisis 2 was for the PS1 console, it brings the best graphics and by far the best FMV cutscenes we have ever seen on this console. Like that was not enough, this was the game that taught me the importance of sound in games. I just could not play this game while i had my surround system set off, I had to turn it on every time I played this, and I had to tune it up higher than ever before.
Gameplay, and the battles before anything are completely redesigned, and are by far the best in the series. The singleplayer CO-OP system is the best I have ever seen, controlling 2 characters at once in this game, it is amazing! Boss battles are not perfect in the terms of f l e x i b i l i t y (like God Of War), but they are the best I have ever seen in a Capcom product. There are also some very good puzzles here, mostly they will occur upon trying to open treasure chests. Like that all wasn't enough, the most sparkling thing in this game are its characters, who are so well made and so unique, that they are to be compared with roleplaying games characters.
It's a remarkable game, even not having the simple ability to jump !
