Stage objectcompatibility (such as the breakable crates in Guile's stage in Street Fighter 2, or having triggers, like let's say that Ryu is trapped in a prison cell, he is freed once the player has defeated the opponent)

Character specific winquotes, such as Ken to Rainbow Mika "What does the R stand for?"

A "choose your path" like in Street Fighter 3: Third Strike.

An option to "mask" the character select icon, to make "secret characters".
