I really don't see Bleach being nearly as content-packed or all-around awesome as DBZ, but it seems to be pretty safe.

When I had initially heard of the DS and Wii Bleach games coming out in the US, I heard that they would be retrofitted (like the Naruto Wii game) to fit with the anime's television run. When I heard that, I forgot about the games entirely (I watched Bleach Wii played in front of me last year--wasn't particularly impressed--, and I own both DS games already). I ain't playin no Bleach game without no Bankai.

Researching the game just now though, it appears that the US version's content will be the same as the JP version--meaning Bankai and Arrancar and all that snazzy jazz. Still stuck with the dub voices, though it could be worse. (DBZ however, with its oodles of characters compared to Bleach's 32, has the option of both English and Japanese dialogue).

I'm probably still not going to buy it :P But at least now I know it won't be gimped.

I can understand your decision to skip Twilight Princess and Metroid and some of the other popular games--you have friends you can borrow them from. Prudent.
