Personally, I just want Abe's chanting to stop making noises when something is possessed (That really bothered me hearing that over and over again after taking control of a Slig), hearing Scrabs, Paramites, and Slogs how they used to be , to change the animation speeds of certain actions like well jumping, entering/exiting doors, etc. and maybe the option to turn off Slig and Mudokon dialogue in the in game options, as those were the only things I really honestly couldn't stand in New 'n Tasty.
On the subject of something such as the slogs, the intimidation factor used to be way, way higher seeing a group of

these vs..what we got in New 'n Tasty..I'm sorry but they just didn't cut the mustard, at least in my opinion. Slogs used to scare the shit out of me, and even as an adult still slightly give me the willies when I go back and play AO and AE..
