Ok for Heartgold, I made a commitment to catch ALL the Pokemon, I wanted to follow the original idea of 'Gotta Catch'em all' before Pokemon America dropped that slogan after realising Ash only filled up like 10% of the Pokedex. And thats what happened, I caught all 493 Pokemon and got my certificate. Hours of leveling up, hours of breeding, hours of finding the Pokemon (Including buying previous versions just to get certain Pokemon), hours of looking up what items/stones are needed to get certain evolution, good job me.
Then Pokemon Black and White came out, I kinda half expected there to be a new Pokemon game coming out with new Pokemon any
