you're just saying that to make you feel better about your impatience.
No, I'm saying that because it's a perfectly legit "concern", as it were.
At "best", we may just have music altered or taken out. At "worst", some Tatsunoko characters that were in the original game may have been taken out and/or replaced, because nothing could have been done about them on the legal front.
I mean, it's not like it's any serious skin off my nose, in any case. If there's enough of a compelling case to be made, then I'll double-dip with the quickness. If not, then I still have my original copy of the game, which I've been able to enjoy for almost half a year now. No fuss, no muss.
