I always found it weird when the most Americanized Japanese games like Disaster: Day of Crisis on the Wii and Metal Wolf Chaos on the Xbox didn't get North American releases.
Anyways, yep, I played it, initially through a softmodded Wii and more "nefarious means," but I ended up buying a physical copy on Ebay since it was so inexpensive. It's definitely a guilty pleasure of mine. It's not an exceptional game or anything, however there was nothing else like it on the Wii. It's one of the Wii games that got me excited for the Wii. Disaster: Day of Crisis, Project HAMMER (I think that was the name), and Sadness. One didn't release in America, the other two didn't release at all. ?
