I do recommend checking out either X or Y as well if you can. It was pretty neat, especially considering that the region was modeled after France. The story was so-so with it, but overall a solid entry.
Also, if you have any of the DS and GBA games lying around, it's worth looking into the Pokemon Bank and seeing what all you can transfer up to Gen 6.
And a side-note... You can play the Global Trade System to get the pokemon you want, too. Only ones that may be a bit iffy to get your hands on might be the legendaries through there, but most of the others, you can trade for, easily. (It's how I filled majority of the holes in my Dex after I finished transferring my pokemon from previous games.)
