Why is this shit so complex? The fact that Easy Mode isn't even available from the start for newcomers and that if you want to beat the game on your desired difficulty, you need another copy of the game (and the right version) is ridiculous. Any other game would've allowed you these from the start, or to start a new save file on Challenge Mode once you'd beaten the game.
This could've been an excellent feature to Pokemon, but Game Freak broke it beyond repair.
