Webfoot Technologies, Inc is a company I've never heard of before but apparently they make all kinds of games, but the one that caught my attention as a fan of the anime series Dragon Ball Z was Buu's Fury for the Nintendo Gameboy Advanced system.
These guys were also responsible for Legacy of Goku 1 & 2. Buu's Fury is the completion of the Z storyline following the defeat of Cell in Legacy of Goku II.
Newly introduced this time around includes a customizeable stat system where as you level up, you decide which parameters you want to improve for each character. Also you can equip all kinds of items to strengthen your character further.
The downside is that this game is far too easy. Characters grow in level extremely quickly and enemies have very little challenge. They threw in a block feature but its really not necessary.
You can play as Goku, Vegeta, Gohan, Hercule, Goten, and Trunks as well as fusions like Gotenks and Vegito. Amazing graphics, great sound and the storyline is pretty accurate to the anime, although they keep things brief.
Its also got multiplayer capabilities if you own a link cable and since its a GBA game, its also compatible with the Nintendo DS and DS Lite.
If you're a DBZ fan and own a GBA or DS, get this game! You should be able to find it for $10 or less at your local GameStop or online. One of the best handheld DBZ games around!
