Personally, I think this is pretty cool. I find the little intricacies of how things change between a demo and retail to be quite interesting.
Props as well for having proper war2 icons. It seems most war2 projects have either an 'updated' take on them (which usually look fine, but I'm fond of the originals), or their aspect ratio doesn't really fit properly in the war3 ui so it looks weird. Since this is Human campaign, I suppose it make sense that orc icons are missing. Would you be able to upload them?
