It took me all of 10 min to beat the "story" for the Dodgeball game, but you don't really play for the story.
Happy to say that nearly all of the original NES game (Super Dodgeball) is here, but simply reskinned with changed music to match Double Dragon. The only thing missing would be the inclusion of an ice level that was present in the NES title. It simply made the court slippery and frankly, it was an annoying level. They did recreate the sand level, making it the only level that seems to directly impact dashing/running. I might be wrong, but there also seems to be more teams to play as, allowing you to play as the various Double Dragon enemies.
I played a level of Revive and didn't enjoy it half as much as the Dodgeball. Still, the little add-on made the purchase worth it for me.
