I spent hours playing a similar game on the Speccy that I've never been able to track down. Turn based with graphics that looked like Lords of Chaos, except you controlled an army of wizards and soldiers against invading swamp/rock monsters. The one distinguishing feature I remember is that you had to aim ranged weapons manually, a bit like a golf game with a rotating direction arrow where you have to press stop at the right time.
