tittle says it all

You can do them again, but it doesn't count towards your total percentage, only new game + percentage.

its just i heard you get a diferent ending if you do all side missions, ive done most and im almost at the end of the game, i wanna know how it finishes the main story but it would be a bummer to do all the side missions again for a true ending, im just missing the riddles.

you can finish the regular game and still finish the side missions in the regular game for the second ending. New game and New game + are seperated completely, except riddler trophies and upgrades.
