I grew up playing the games, and still have my copy of Yellow and Red. I fell of the wagon somewhere around Gen VI, the games just got to easy. It became clear to me that Gamefreak was just throwing in the towel and gave up making interesting games.
That being said, recently I started getting into the world of Romhacks and they have sparked new joy in me. The games are hard, fun, and have a lot of love poured into them. I'm going through Radical Red right now, and its been an incredible time.
