Is it because less and less retailers have room for RPG gamers? I differenate RPG gamers from CCG gamers because last year I talked to a local retailer about demoing a game there and he said and I shit you not " I don't like having role-playing games played in the store because it annoys the card gamers.". He sold RPGs at his store. Had plenty of room to play RPGs at his store. Go figure.
Another thing that could be a hinderance is finding other players to play. In hind sight, I can see that being a problem. The many complaint I heard from those who talked to me at this cons was , unless it's D&D their group didn't want to play it. Is this an isolated thing or trend?
