What is noticeable are the changes made in some of the graphics. Not everything has been modified, just a few towns, trees and creatures. This may seem odd, but the changes aren't so big that there's any great inconsistency between the old graphics and the new. The towns of Jasper and Barloque have both been given a facelift, and considering the limitations of the creaky old engine, the artists have done a pretty good job. In fact, I can't see the graphics getting much better without some pretty big modifications to the engine.
Buildings look smarter, more detailed and even, wait for it, a bit realistic .
The hedges in Barloque in particular look as if they've been painted onto a cardboard box. Some of the monsters have also been treated to an update, with the giant rats in looking far more fiendish, even if they still become a gunky blob of pixels when they get close. There are fortunately some more new creatures, the most interesting of which is the groundworm larva. This potters about just under the earth's surface until it senses you at which point it jumps up and bites your nadgers off. For some reason the 'dynamic map' or 'radar' to us simple folk still displays the larva when it's underground, and you can't even walk over it.
