I've been loving the quests feature in Classcraft. So far, I've built a whole fictional narrative around the warriors, mages, and healers, finding ancient technology that they are trying to power up and help the locals, (think the Ancients in Stargate meet World of Warcraft). I then try to tie the real-world connections and community in the tasks.
Students are really beginning to get into their imagined persona in the quest narrative, while also getting into how the technology or tool they are learning about can help them, their community, or help people solve problems.
Are there any others who have experimented with quests in computer science, digital arts, animation, electronics, or technology spaces? I'd love to hear about your experiences as well.
