A cool, free app, but not too deep.
Gameplay: Well, obviously, there isn't much gameplay in here, since it's just a Pokedex. You can see the Pokemon from the 5th gen, so it's a good strategy Nintendo uses for people to meet the new Pokemon and buy the game. However, you have to actually "get" the Pokemon. You do this via spotpass and also by scanning some pokemon qr codes which you can print, and then you can see your Pokemon in augmented reality. The lack of Pokemon from other gens takes some points off, but it's not too bad.
7/10
Presentation: The presentation is kind of on the mediocre side.The 3D is subtle. The graphics aren't the best, but the Pokemon are well made. Something bad is that the backgrounds don't change much, and there's no music, which gives a sense of emptiness. The Pokemon can make animations and overall the presentation's good for a free app, but it's not something you'd pay for.
5/10
Replay Value: Obviously, you'll be coming back to this app to receive new pokemon. However, there's not really much to do with it.
5/10
Fun: I didn't have too much fun with this, and it kind of dissapointed me. On the bright side, the graphics are nice, and it's free, so give it a try if you can.
6/10
Overall: If you have a 3DS, download this. You'll enjoy seeing the Pokemon, and it's interesting especially if you don't know the new Pokemon. The presentation's lacking, but this is free, so download it now.
