Its worth it, great way to play with others
Story
You basically stop the stupid looking villians again, who wanna recreate the world. Not a bad storyline, but it should continue after the elite four so that you have something more to do, other than catching the 4 more non event legendarys. After the elite four you have two thing to do. Catch pokemon, or the repetitive battle tower. Rating 7/10 Underground and other minigames
Now here is something that keepsyou playing when you beat the game. Ive spent 1/3 of my time in the game underground. My friends and I like underground more than going around and repeatedly beating the elite four. There are very many different items that you can add to your base. ive decorated my base 100 times differently. Then comes the poffin house. The main ingredient to winning contests, another minigame. And there is also Pal Park, a more fun way to get your migrated pokemon. its not hard to beat your rivals score. Then there is the battle tower. Not so fun after you have fought all of the trainers there, because they will reapear with the same pokemon. 9/10
Ds capabilities
They didnt exactly use the touch screen to its max potential. They could have had puzzles you solve with it, or anything to do with unlocking things. There was the ever useful poketch. It has a few peices of junk on it. not much fun. There was the poffin house, however, which used it to stir the poffins. Then there was the underground mining which was fun. And contest dancing, which reminded me of a DDR ripoff, not bad but not great. 8/10.
New pokemon
Actually theyu seemed like some of the old ones in usefulness, Pidgy - Starly, Rattata - Bidoof, Torchic - Chimchar, etc. It like the old ones with a new skin. It makes it fresher, but not better. There were a few new pokemon like Shinx who didnt really remind me of another pokemon. There are some that made it through the entire pokemon series, like Magikarp (SUCKS, not gyarados though) Zubat, Onix, Geodude, Machop, Psyduck, Gastly(always one of my favorites), Goldeen, Ponyta, Chansey, Clefairy, Pikachu, Snorlax(My very favourite), Marill, the obnouxious Tentacool, and some others if i forgot. These are those only from nationaldex and it includes their evolutions.
