The game looks really nice? And, for the first hour or so while you get your city off the ground, it doesn't play that badly. But start to get deeper into it and you will find that the series of challenges Imperium Romanum presents seems to be made up of overcoming the game's flaws rather than its scenarios. The gameplay is very basic and badly dated and, with all the top-end city building sims out there now, that makes it doomed to failure.
With very little in the way of redeeming features, it is only going to have any kind of appeal to the most hardened of Roman history vets – ones who don't know games very well so won't know better.
