I always play differently. I almost never use legendaries, and I usually take my time and balance my team. It's always been more rewarding for me. The only time I've ever rushed through a Pokemon game was the second time I went through FR/LG (yes, I had both games at separate times). I just wanted to clear through it so that I could transfer Pokemon between it and Emerald. That's not to say it wasn't fun; it was a blast plowing through the game with just Charizard. Another reason why I did it was because the first time I played LeafGreen, I had simply not trained my Pokemon enough for the Elite 4, and I had to trade in a Level 100 Gyarados from my friend's game to clear through them.
