Victorious Boxers 2 is a very confusing game. Not in the sense that it's hard to decipher - what's actually on the disc is a pretty straightforward boxing simulation based on a popular Japanese manga. The difficulty arises when you want to read up about it over yon interwibble.
The name suggests that it's Hajime no Ippo 2: Victorious Road, a handsome-looking boxing title with branching storylines and a boxer-training facility. In actual fact, it seems to be that game's predecessor, Hajime no Ippo - The Fighting! All Stars, which doesn't seem to branch and doesn't mention training at all. It doesn't help that the game's publisher, Xplosiv, seems to be rather light on details about the game on its website right now.
No matter - you're concerned about what it actually is, not what it isn't, and you're equally unconcerned about how your dutiful reviewer spent half a week bouncing off the walls of fan-sites and bellowing at Google in an attempt to put it in some sort of context.
