I think that if Paradox were ever to get back to expanding the timeline of their grand strategy games back into the ancient world, they should do it as a whole new game, with a much grander focus than just "Rome". To be honest, Rome by itself does not make for a very interesting-sounding strategy game - they are rather over-powered, as zorkman was suggesting. However, if you extend the timeline back to, say, 626 BC, now there's a lot of potential for interesting gameplay. How about leading Babylon to conquer the entire Near East? Or fighting against their rise as the Kingdom of Judah? Now that could make for a fun game! However, in order to do justice to such a grand endeavor, it would have to be its own game - it can't just be a rebranding of Europa Universalis the way that an EU: Rome II would be.
