i agree with buwiset,Ninja Gaiden dragon sword is an awesome game but so is the legend of Zelda:phantom hourglass and assassins creed: Altair's chronicles.

metroid prime hunters is also a good 3d game

the best character in dbz ss2 in meta-cooler and (evil) majin buu.

their attacks awe awsome and 3 of buus special attack can kill anyone.

my other 2 favorite characters are broly and cell (final form)
