Fair enough. I put down 3.5, which I'm running, but also 1E, because I think it's probably the closest to C&C, which I'm also running. (And which will probably have a bunch of Pathfinder tweaks added to it ...)That might be worth while, but what I want to avoid is people picking "other" rather than BECMI, just because they are using house rules, or some parts of another system. Maybe a better question would have been "which of the following best describes the DNA of the Version(s) of D&D you are currently playing?"
