Brian said: Gold, I'm pretty sure Simon is talking about games that are less popular, so you see them less frequently. Not campaigns which meet infrequently. Exactamundo. You can effectively find a game for the more popular games, such as Pathfinder, or 5th Edition DnD, without an issue, almost constantly. However, the more obscure games are rarely run, due to their nature of being obscure. Some people herald certain obscure games as a nugget of wonder, a divine penultimate collection of rules and setting. Thus, when someone runs such a game, those ravenous fans of the system might jump in feet first without bothering to read any commentary other than someone is willing to run the game. For example, how many times have you seen Wraith: the Oblivion run via Roll20? Chances are, not very often, yet there are some diehard fans that would jump at the chance, regardless of what you stated in the campaign description. You could probably preface it with "During the game, I will be playing a mixture of polka and Kenny G, there will be a baby and a vacuum cleaner providing background noise, and I will periodically fall asleep in the middle of running the game." and you would still have people salivating at the chance to play. I apologize for my lack of clarification, and hope this illuminates my original intended message.
