The convention focuses on "the craft of LARP", offering discussions, panels, and workshops about writing, producing, running and playing larp in all its forms, as well as related crafts and skills such as costuming, makeup, dance, and weapon-making. The focus tends to be practical rather than academic. The conference also hosts a Build Your Own Game seminar.
NELCO is supported by NEIL.
