Classic Mode

Classic Mode is a mode in Super Smash Bros. Melee and Super Smash Bros. Brawl that serves as the successor to the 1P Game in Super Smash Bros. The two modes are virtually identical in order; however, certain changes have been made. In the original, the player fought in a predetermined order: the player would always fight a specific character at a certain stage in a fixed order under static conditions). In Melee, randomization elements were introduced - the battles and the order in which they are take place are, for the most part, completely random (other than the basic layout, which is elaborated upon in the below section).  Additionally, the Board the Platforms bonus game has been removed, instead replaced by Snag the Trophies.

Interestingly, Classic Mode (in Melee) is actually shorter than the 1P Game in the original.

Battle types
Classic Mode introduces different types of battles as the player progresses. In Melee, there are is one type of each battle in a set stage while in Brawl there are multiple special battles fought randomly in each stage.

Regular battle
In a regular battle, the player engages in a one on one battle with another character. These type of battles are the most common type of battle in Melee and Brawl. The opponent is usually chosen at random and is battled on their home stage.

Team battle
In a team battle, the player pairs up with a computer ally and battles two other computer opponents. The opponents and ally are chosen at random in Melee, while characters of the same series usually team up in Brawl. The battle is usually fought on one of the opposing characters home stage. The higher the difficulty, the less reliable the ally will be.

Giant battle
In a giant battle, the player pairs up with at least two allies and battles a giant character. The giant character will have the same attributes as a character with under the effects of a Super Mushroom, however the enlarged size will last the whole battle. The giant character can usually sustain more damage and has more powerful attacks, but their jump is distance is reduced and they become a bigger target. The higher the difficulty is, the less reliable the computer allies will be. In Brawl, the player may have one computer ally or none at all.

Multi-man battle
In a multi-man battle, the player fights ten copies of another character. The opponent team will attack in groups of three, but their weight is lighter than their normal version.

Metal battle
In a metal battle, the player faces an opposing computer player under the effects that are similar to the Metal Box. A metal character can sustain more damage and are less likely to flinch with more powerful attacks. However, their falling speed is increased and running speed reduced. In Melee, a metal battle is always fought on the Battlefield stage with no items appearing at all. In Brawl, however, the metal battles are chosen at random by series and items are present.
