>>34348416I don't think I've ever really kept close to a release of a pokemon game, but I do remember when DP was coming out that CN did a full, multi-day marathon of every pokemon episode from the anime to hype up the new season at the time.
Also I remember a local mall was doing an event for BW which was the only pokemon event I ever went to. They gave out a shiny Suicune while GameStop gave out a Celebi. They also had demos for BW which I remember just being blown away by, like, "Whoah! CG environments in a pokemon game! This is it, it's not gonna get better than this!"
