For the INTJ's: Even though INTJ's do in fact make up about 1% of the population segment, it is understandable that there would be a disproportional amount of INTJ's here... precisely because it is the (scientist) engineering type personality. Because boardgames often involve many constructive characteristics (especially in design)... it lends a point of credibility that there are so many INTJ's here.
Signed,
an ENTJ (LOL)
Yeah, some types are more common then others according to the M-B (as well as other personality tests I've seen). I guess thats something I always assumed as well. Though I agree everyone is unique.
