it looks an americas animal pack, what do you guys think?
Most likely.
It was the most requested theme for a DLC after the less realistic 'all birds' and 'fully aquatic'.
So, good choice for the DLC theme, but I feel they could have picked better animals (but let's wait to judge until we know the full roster. If the final two are coati+mara, I won't complain)
Either way, this DLC doesn't feel like the final one. Every is still waiting for the secretary bird and tree kangaroo (and walrus, but I doubt we'll see that one)
