Whether you play this competitively or just for fun, this game is a must buy for Gamecube.
Gameplay & Other Things - This game offers the "Classic Mode" which
is the mode that was played in the original Super Smash Bros. You go
from stage to stage battling characters. After you defeat a character
you move onto the next stage. Also in classic mode are 2 minigames.
These are Break the Targets, which basically involves you trying to
break all the targets within a time limit. Each character has its own
unique Break the Targets stage. The second minigame involves you trying
to hit trophies falling from the sky into the target zone. "Adventure
Mode" is the mode where your character travels through Regular
Stages(Like the ones in Classic Mode), or Adventure Stages(As I like to
call them). In the adventure stages you start at one point in the
stage, and must travel towards the other end. At the end instead of
battling the Master Hand, you battle Bowser. When you finish these, you
can unlock a third gametype which involves you battling every single
character in the game. The other single player game types are Event
Matches, and minigames like Target Test, Homerun Contest, and others.
The single player is great, and worth playing. 9.4/10
In multiplayer there are many gametypes you can pick from: Special
Melee, Tournament Mode, or you could just play regular melee. With all the items in the game, and the ability to customize which items spawn, and how frequently, it adds a lot of depth. You can also choose how the maps rotate, which maps rotate, and what maps are randomly selected. When you play in multiplayer mode you earn coins depending on
what happens in the game. The coins can be used to purchase
trophies, which are randomly chosen. Trophies have no real value except for bragging rights. The advanced techniques also add a lot of depth and replayability to the game as it takes time to master. 9.7/10
Sound - The soundtrack for this game is amazing, and was topped only by Super Smash Bros: Brawl. Each stage has a unique soundtrack that plays in the background. 8.9/10
Overall, I would rate this game a 9.5/10 and would recommend it to anyone.
