Gen 4 is for me a mixed bag, it plays very slow, many pre- and new evolutions to previous existing PKMN bother me, but it also can shine very bright. For example the starter lineup even outclasses Gen 3, the Battle Frontier is added in Platinum (big plus for me), the new region is cool (literally), easily the best champ fight in the series thus far, and the extra plot w in Platinum is fire. I really think this game challenges Emerald for the number one spot but it isn’t quite there. Nevertheless a very good PKMN one of the strongest.
