And we see the biggest split happen at the bottom in what were niche games - Icewind, Torment, and Wasteland. You may have loved them, but they were not block busters in how many people play them.
With an average of about 10% difference in play experience on the major games and a ONE% difference in those who have played D&D that does not support a 30% difference and a 1 -> 10 flip on hate/love decisions at all by tacking it to experience. From what I can see. Anecdotally, being on both forums, I would not walk away and say only smart, technical, experienced, knowledgeable people are on here or even say that the comments reflect a majority of more experienced individuals.
BG1/2 and FNV aren't that behind DOS1/2 either.
I an pretty sure that this questionaire if posted on GoG and Steam would have different results.
