I don't claim to not understand this passion some people feel for one console maker over another. I myself have at one point have felt a special loyalty to a particular game making company. I've been playing video games for a long time, since the Atari days, and from there to the 8-bit systems to Sega Saturn, Sony Playstation and likely the soon to be released Sega Dreamcast. Or is it because that is all they know.
Lets face it, video games can become an expensive habit, with tabs easily running to the thousands.
For most, the choice of having multiple platforms is not an option for economical reasons. So they can only choose to support one console. And because it's human nature to always want to have the best and wanting to believe what one has it better than the next, it's natual to turn a blind eye and even to critcize others for disagreeing with their choice out of fear of having made the wrong one. And to confirm their believes they would actively gather opinions to affirm their choice and put-down those who would dare to have a different opinion. Of course I'm probably over simplifing the many reasons why people would feel a strong loyalty to one particular company.
