Excellent for Middle School and above. Great way to keep students engaged, and on-task, give autonomy in learning paces, etc. Students love the avatars and pets. Formative assessments and quest tasks are compatible with Google Classroom among other formats. It's the best. Review collected by and hosted on G2.com.

The downside would be how time consuming it can be to set up initially and write out the descriptions. I haven't found a way to import assessment questions into the battles; they must be typed in individually. Review collected by and hosted on G2.com.
