It would be more motivating if the special items on the very last stage were better. It is a kind of trophy to put in your underground. It should be really strong so you could be proud and happy with it. But that is the same story with all the camp equipment wherever you look. I think it’s what my son calls „suffer to play or pay to play“.
As long as you can earn green rings and amethyst, ruby etc. that’s motivation enough for me to take part.
