I think racing would be a cool one; if course, it'd consume waaaay more space BUT! It can be down a slope, like Angry Birds Go [ik, how original :P] but the trick is: You use your dragons! Dragon powerups is dependent on what elements it has. Let's say you use.. Steampunk Dragon for it. Steam would use metal/fire powerups. Level and rarity also plays a factor. Rarity increases speed gain, while level boosts max speed. Comment to this area to list other games/activities would be a cool addition
