well, exploring is a pretty big word. i mean, arkham city gave you lots to explore too. but really, if it wasnt for the riddler, there wouldn't be much reason to explore the town at all.
its not like i can't appreciate the good things or something. i love how trading and battling others seems to be much easier and intuitive now, but without new pokemon, there is just something missing. I mean, I think, we're at 18 megas and 70 new pokemon? that sounds ok at first, but then, if you take away evolutions and just go by species, we're at 35 I believe. 35 new species of pokemon really seems a bit low. And there really wont be much more than that, at least if we base that assumption on zygardes pokedex number 718. Lets say theres another mew like pokemon afterwards, that brings us from 649 pokemon to 719, making a 70 pokemon difference... thats really the lowest they've ever gone.
