This game is absolutely amazing, with all the new additions, this is the best Pokemon game so far...
I say that this game gets a perfect ten because with its new additions, 490+ Pokemon, improved storyline, and enhanced gameplay, this game is absolutely perfect.
There are many cool new features including being able to catch Dialga, Palkia, Giratina, Heatran, Articuno, Moltres, Zapdos, and more with events.
There are also changes in the storyline including adding a new team galactic member; also, there are more things you can do after you beat the Pokemon League.
If you have not yet played Pokemon Diamond or Pokemon Pearl version, you should know that the gameplay is absolutely fantastic. This game is highly addictive, and before you know it you'll see you have altogether player longer than 25 hours.
From the beginning of the game to the time you beat the Pokemon League, it creates my estimated number of 19 hours of gameplay. If you enjoy Pokemon games, you will most likely be pleased with Pokemon Platinum.
