I love that game! It is a little light on the resource management / building aspects mentioned, focused primarily on battle (iirc you can't build anything, just capture villages which generate the one resource, gold). Though there are lots of mods that bring it closer.

Many hours on that as a kid since it came free with the distro of Linux I had access to at the time. Good memories. I got into pixel art from trying to contribute something to the project (most of it was rejected, haha).
