Platinum was great, but it wasn't Platinum that got me out of my "Pokemon Drought", so to speak. I honestly thought Pokemon was over at the time, and new ones weren't being made, how wrong I was! Anyhow, Diamond was just a great playing experience, the Pokemon introduced all boasted excellent designs, save a select few, and the plot was decent as well. Pokemon Diamond was everything I could have asked for, at the time, and I had a great amount of fun on my first playthrough. Platinum boasted a few improvements, but nothing significant enough to 1-up Diamond.
