So I had the original SuperPower years ago and enjoyed that, so couldn't resist givign this a try. Had the same kind of fun conquering the Middle East, then hit a bug that basically broke the game.
For some reason I forgot to invade Kuwait on my march through the sands. Aiming to correct that oversight, I promptly sent my troops and no sooner did they arrive, for some reason the game reverted to the opening start menu of the game, same as when you first load it up. The move troops icon was still there too. Loaded my last autosave, proceeded to invade Kuwait again, same outcome. A bug loop that can't be rectified and is effectively "GAME OVER" for that save.
Such a shame, as I could live with the occasional crash to desktop I encountered here and there. It's an old game, of course, but when ancient Kuwaiti bugs like this hit, well, it's time to uninstall and forget about it.
