Do not bother with Diamond & Pearl, just play Platinum. The game engine is atrociously slow, especially during battles & surfing. The Physical/Special split is not enough to save this game, especially when most of the new Pokemon are locked to postgame which in itself is also bland. We excused the flaws back in the day when this game dropped since it's all we had at the time, but in hindsight the flaws are simply inexcusable. This is the one Pokemon game that feels like a beta version rather than an actual product ready for release to the masses.
