Can someone explain the conjugation of “manger” for i, you, he/she, they, we, and you all? you.

Late editis this french setence grammatcally correct? "vous aimez dessiner, prendre des photos, jouer aux jeux vidéo et les animaux. alors, je pense un bon métier pour toi est un jeu vidéo designer." en anglais: you like to draw, take photos, play video games and animals. so, i think a good job for you is a video game designer.question: in the phrase "jouer aux jeux vidéo" should i add an -s to vidéo? why dont i have to conjugate dessiner again? consciously i thought it wasnt supposed to be conjugated but why? no translators, .
