I picked up Okami for theWii, and it's been quite a fun experience. The motion controls are a little twitchy and take some getting used to, and your companion in the game, Issun, is mostly annoying. Everything else though is excellent. The graphics are gorgeous and really make me feel as if I'm walking inside a painting. The story is different enough from anything else I've played that it mostly feels fresh.
Here's the thing though.
I've played for around 21 hours or so. Very suddenly, without much warning, I was plunged into a pretty epic fight with the main antagonist. I was a little puzzled at this. As I progressed through the game I picked up various abilities that allow you to use your paint brush to perform different actions. There are 13 total actions, but at that point in the game, I had found 9. I also knew there was a whole other city that I hadn't gained access to. I thought that maybe the game gave you the option of finishing it without finding all of the powers and other content, which would have been very different from any other game I've played before. Alas, it was not to be.
I killed the bad guy, saved the day, everyone was celebrating. And then the game kept going. Apparently, some other evil wormed its way out of the original bad guy's rotting corpse and still needs to be put down. And to be honest, I'm not sure how inclined I feel to continue.
At this point, I feel like I've experienced the whole package. Sure, there are 4 more brush powers to find, but I looked the game up on GameFAQ's and it appears that I'm barely halfway through the game. What new stuff can there be to sustain another 20-30 hours of playtime? The story, being heavily influenced by ancient Japanese mythology, is different, but it still boils down to saving the world from the Great Evil. I've saved the world several times over at this point in my gaming life, so that's not a great motivator.
It doesn't help that while continuing into the next area, the Wii froze up about an hour after I had last saved my game. I thought only Xbox 360's came with that feature. :-(
