Time to have a Magicarp follow!

Possibly going to be the best Pokemon game, ever.

Saw it on GoNintendo. Its cool that all of the Pokemon will be able to follow you around.

This remake better surpass the original. :D

I thought they were adding pokemon merging looking at the picture, LOL.

Wow, this is certainly more than a half-hearted effort.

This looks way better than the remakes of Red and Green.
