A play is basically a long, formalistic polemic. You can write it without the poetry, and if you do, you may have a pretty good play. We know this because we see plays in translation. Not many people speak Norwegian or Danish or whatever guys like Ibsen spoke, or Russian - yet we understand Chekhov and the others.
