it depends on teh area---at my local McVans (used game store)
there is a guy that knows every up to the NES --huge Atari nut
then there is a guy who lives and breaths the DS
also have one that knows the 360/xbox better then his own name
and the other guy at the store is a big ps2 fan--not Ps3/Ps1 for some reason
Nothing on the Wii....which is sad
