RoboMasters the Animated Series
|
Groups of people chilling (but not really), learning about teamwork, and building mechs.
RoboMasters is set in university and is based on the irl competition RoboMasters. Classroom Crisis is set in the future with space drag races, big bucks, and big dramatic plots. CC is grander in scale whereas RoboMasters is essentially a down to Earth school club show with cute little robos.
Neither are life-changing masterpieces and neither stands out much over the other execution-wise, both are enjoyable but underwatched. If you liked one, give the other a try.
