The new one gives the illusion of texture. That old one from your screenshot, Nilo, seems more like scorched earth, than a rock. Re-implementing the old one would be a step backwards, in my humblest of opinions.
Must be just me because I started playing a day after the new client was released, but I was happy to not see the graphics I had previously seen in screenshots from the old client. I didn't like the old graphics. Personally I think that the newer ones are equally horrid in comparison to the old ones, although at least the graphics appear conform now.
In short, retro-production (in the case of Illarion's game graphics) sucks, and I'd rather see things move ahead...
you mean using a program that can edit the graphics in the exe and then replacing it with the old ones by somehow getting a copy of the old graphics? Though I'm not sure if that'd work right....
