Thank you so much for your opinions!
There have been competitions here in Norway too, but it seems that there were too few groups who would participate, so I think they stopped with it all together, which is really sad. But we're hoping to maybe inspire other people to make cosplay/skit groups, so that the cons will start hosting skit competitions again.
And it's not usual to hire cosplayers to do performances here either. We have been told that we are the first group to be hired by a con here in Norway. So the pressure to preform well is big!
