Then what year did he debut? I was around during this time, and I don't remember Sonic until later after DK Country. The thing with video games is all relative to an individual's memory just like music. We can talk about video games for an hour and still get nowhere because our tastes vary so much.
Btw it was 1991. Most of us are at least 50 in this forum and like me, our memory is not as sharp as it used to be. For example, Alex and Chris, famous wow lore writers, could not remember all the detailed storylines at a Bliz Con panel years ago when asked by the Red Shirt guy. I guess too many visits to the Cosby suite must have fogged their memories for good during the weekend.
Guess who has an in-game WOW character and who does not now?
