A good game should be fun to play, be a challenge to build, and provide problems to solve. There will always be robot designs that are super complex and elicit “parent/mentor-built bots” comments (this is true even in VRC, FRC, etc.). Even Next Level is no exception. It was a super easy game to play… and the Vex standard robot, Flex, was able to play it extremely well. But even in NL, there were robot designs that were more complex than others.
I think the point of “more non-student centered” has more to do with coach/parent involvement and to an extent clone robots from the same organization as opposed to the game itself. I remember watching a Youtube video from Bankshot, and it was from an elementary school event in the UK. I think an organization from China participated with a couple of teams, and both had the same super complex robot… and the parent or coach was quite involved in coaching the student what to do, etc.
