Believe it or not lads & lasses...the average gamer on pc's is between late 20's up thru the 60's...
Why? Because we were the ones who started out with our Commodore Vic 20's back in the late 70's & 80's...we were there when Duke Nukem was a side scroller...ran around Castle Wolfenstein...hopped in our X-Wings and TIE Fighters...saved mars and the earth before we were DOOMed...etc...
We were there from the initial launch of home pcs...my first being a Tandy HX 1000 to a Compaq 33Mhz(yes you read right) that cost my father back then 3k...my first home built was an AMD 233Mhz...
Younger kids are more the console generation while adults seem to be more pc oriented...not to say either side switches back and forth from one platform to another, but I doubt kids these days would enjoy my Intellivision or Atari console...lol
