I just made a role play guild based off of Half Life 2. In it you can play as one of the many rebels, thus experiencing the world of HL2 differently. I still need some work on it, but the more open minds there are for it, the better, so who would care to join?
(note that it is much more advised that you had played the Half Life series before hand, otherwise you might get kind of messed up)
