I agree with most of the comments here…my suggestion would be to classify boxes on a spectrum, with one end being Full-CTF and the other end Ultra-Realistic or something like that. The reasoning behind a spectrum would be so that users can vote on it and also because certain boxes aren’t clear-cut, e.g. the user part may be pure CTF but the root part may be realistic. It would work kind of like the difficulty graph, with user votes giving a realistic depiction.
It would have nothing to do with difficulty or points, it would just be an extra metric to give people an idea if they should waste 2 days on a box or not. CTF boxes may be fun, but they’re a frustrating waste of time for people who need to learn real-life skills or prepare for certifications like OCSP.
