Geeks — including gaming geeks in particular — are not any more or less dysfunctional, on average, than the general populace.
However, as with any group, there is a core subset of uber-geeks who take games very very seriously and get very upset about sequels to their cherished games — sequels which cannot possibly live up to the image of the game said geeks have constructed in their head. Hence when a company like Blizzard announces that it's producing Diablo III, latest in an insanely popular clickfest crpg-lite, many Diablo fans react roughly the way Al-Qaeda would if you published a cartoon in which Muhammad wins a hot dog eating contest.
Hence a furious and interminable argument about the art direction and visual style of the newest Diablo, culminating in a hilariously entitled and irritable online petition to Blizzard complaining that the new game will be just too fucking pretty.
It has a list of demands headed What we want. It also has a list of complaints:
Outside scenarios with vivid colors, beautiful forests with colorful vegetation, shinny and beautiful waterfalls where even rainbows take place.
Oh, won't someone think of the imps?
