Soul Calibur 2

Fighting game from Namco. Played on Nintendo Gamecube, also available for PS2 and Xbox.
Tekken with swords. And consequently better than Tekken too. Side stepping is more fluid, parrying with a designated button feels alot more responsive, and with the huge variety of weapons characters all feel very unique; there's the well rounded guy witha samurai sword, the ranged fighter with a pole, the short range fast ninja with kunai, and (my personal favourite) the slow knight with an oversized demonic sword, among many others. A cool addition is console exclusive characters, with Link for Gamecube, Spawn for Xbox, and (lol) Heihachi for PS2.
For a fighting game, there is quite alot to do; largely thanks to the weapon based combat. Each character has a variety of weapons to unlock, which mainly means playing through weapon master mode: a huge map full of fights, with different winning conditions such as guard impacting the opponent, or ringing them out. Ring outs are another element added: you can win by knocking your opponent out of the ring, so it is more imperative to be aware of your position in the ring than in many fighting games. Weapon master mode does get repetitive, however.
Graphics and sound: fantastic. Overall: 9/10
