I think AO's secrets are more challenging and more harder to find. I didn't like the soulstorm bottles that gave away the secrets in AE, it made it too easy. Just the slight change in ambience in AO was enough to make you think that there is something different about a particular screen. I also think AO was more original, the creature designs were fantastic until fleeches were introduced, it's not that they are difficult to survive from, it's the fact that they have plagued the natural habitats of the sacred creatures, it felt like the vaults in AE were more dedicated to the fleeches rather than the Scrabs and Paramites, so it drew a lot of attention away from the 'worshipped' creatures which gave the first game its original, dark atmosphere.
