The job boards are always full of the same posts. "We are creating a game, no money now, but glory will be yours...etc."

Things to check:
If there is no website with it's own domain name then you know the person is not willing to spend even $9.99 a month to create one.

You can check the person's profile if he is posting here. Does he have anything of his own up? Images? Models? No?

Congratulations you've discovered a person with directoritis! People with this disease are prone to grandiose schemes that have few details. They like to collect groups of people and appoint tasks. Unfortunately they are not competent to direct themselves, let alone a small group.

People with directoritis lack the skills to integrate the resources they suck up for free into a cohesive whole. Eventually some member of the unit gets tired and tells the director where to stick it. At that point the director decides it's the member's fault. The director may try to limp along replacing members as they bail, or throw up his hands and abandon the project. Sometimes the director will start new projects. Eventually he becomes convinced that the world is full of ingrates, unworthy of his genus. He will then move on to the Department of Motor Vehicles or some other bureaucratic position where he has limited but absolute power over an individual. 

Fortunately, carriers of directoritis rarely move out of their parent’s basements and mate. The disease is spread by childhood permissiveness and the inability of parents to say No. Consider yourself lucky, Directoritis is spread by association and mental contact. Remove you self from contact with such people and stay sane.
