It's got great graphics and is easier to play, but it still lacks something the first one had.
The creatures in BW2 don't have a personality any more. You never see them notice you and wave with a big smile on their face (I miss my ape).
In BW2 you literally tell the creature to "never eat people" and it never will, like filling in a form or something. In BW1, even after extensive training my ape would go and fart on people

.
All bells and whistles, no soul.
