LLX i thank god it isn't the legacy of Vegeta - cause then it'd of made me so sad ... cause it was just so pathetic.
but then Budokai was also pretty pathetic ... infact the best DBZ game i've ever played has been Bid For Power, which Funimation slapped a cease and desist order on (morons).
However i'd suggest if you base you game on anything, base it on DBGT as that isn't the property of Funimation and there are no legal binds to using the characters within in the same way as the Candian company that reedited for UK (and now US) TV are the same guys that did Zoids, and are pretty open as they don't rely on huge dividends from large licences like Funimation did (which is particially why Toei Animation awarded them the contract for it)
Secondly unlike Funimation they've not cut it up several ways from Sunday, a recent episode where Goku gets naked and swims around and the fact there is the 'damn' word and a few other are now in there.
unfortunately it is only small percent of the original cast from DBZ, but hopefully they can Chris Sabat over to cause i liked his Vegeta voice (they have him on the pay roll so i think its probably a problem with Funimation as both DBZ and DBGT were being voiced at the same time)
Though i think its cool they got Mathew (can't remember last name) over for Trunks, cause i liked his voice for future trunks ...
i'd say concentrate on a good story, but remember RPG style battling and training is a huge part of DragonBall
so make sure you plan it well.
