Soul Calibur Legends follows the story of Siegfried, and expounds upon the story between the games Soul Blade and Soul Calibur. Along the way you meet several more characters from the Soul Calibur Universe.
Ultimately, how you view this game depends purely on your preferences. Soul Calibur Legends shares characters and a storyline from the Soul Calibur series - that's it.
Let me try it this way: if you like Streets of Rage or Final Fight (which I do), you'll probably like this game. If you liked Sword of the Berserk, you'll be extremely familiar with, and enjoy, this style of game. If you're a hardcore Soul Calibur fan yearning for a more in-depth back story than what the Soul Calibur series provides in character endings, you may or may not like this game. If you're looking purely for an in depth combat game for the Wii like... hmm, oh, the Soul Calibur series, you will not like this game. And as we see from previous reviews, this is generally the case.
As far as action games go, the story arc is fairly in-depth; though, compared to RPGs, the storyline is almost non existent. The game assumes you know these characters, so there's very, very little character development for playable characters. Sometimes irritatingly, we learn much too much about the NPCs.
Repetition is the hallmark of beat 'em ups. There's no getting around that, otherwise Final Fight would've been a five minute game. If you're not a fan of or cannot tolerate mindless repetition, steer clear. Where this game shines is the combat system, which is tailored beautifully for the Wii.
Instead of the repetitive button mashing, almost all fighting controls are done with the nunchuk and wii-mote. Quickly flicking the nunchuk will have you strafe and dash, and moving the wiimote will result in an attack.
Let me be clear: there isn't much else past this. The gamely relies solely on these mechanics for enjoyment. There's no alternate configuration, i.e. using the gamecube controller. Quite frankly, if that were the case, this game would be exceedingly dull.
Finally, you need a bit of patience as Siegfried is a bit of a slow character, so the true enjoyment of playing isn't with him but with faster characters unlocked later, such as Lloyd, Sophitia, and Taki.
The good: The combat is surprisingly satisfying, since there's a tactile element (duh) that other games of this genre lack. The storyline is interesting, in that it fills in some of the gaps in the Soul Calibur universe. If you remember the mission mode from the SC series, the missions are set up in the exact same fashion, and finishing a mission averages about 10 minutes - a good amount of time for 'get in, get out' casual playing.
The bad: Because there are a lot of enemies, you'll find yourself with the dreaded 'wii elbow'. I can't imagine playing this game for several hours straight, since fatigue does affect the gameplay. The missions are too repetitive (you'll find yourself in the same locations fairly frequently), and there are too many of them - this kind of genre almost requires the game span to be short, which this game is not.
The gist: the actual gameplay is where this game shines, but Namco dulled it by making too much of it. Thankfully, missions are short so you can play when you please, but don't expect to finish this game anytime soon. Four stars for gameplay, three stars overall for the game.
