I played this through twice to make sure I wan't missing anything, but I didn't. It's one-dimensional.
Not due to the graphics, frankly I'm not impressed with detailed graphics, but due to the gameplay. The goal is to unite Egypt. But there's only one way to do it: conquest. You can't unite through trade, you have to conquer everyone. Mostly by force.
I prefer a variety of methods.
Yes there are targets and you have to achieve certain things in a certain timescale, and to actually do so is a challenge, one you'll get better at each time you play it, but the gameplay is one way only.
That said, there is a certain charm to the game that comes from the lack of intense graphical detail, but its replayability is very low unless you want to continually do better each time.
It's not a dire game. It's simple to learn and, for those who like to be challenged, has timescales to meet. But it's not for me.
With a little more variety in achieving the goals set, and little less focus on repeating history, it would be better. However, judging from the designers objective's, teaching history is one of the main aims. To that end, it would be a useful game for teachers of 8-12 year old children and I would encourage the designer to approach schools and educational software makers with this game as it would fit in with most curriculum. It may even be feasible to sell it it on disc via the British Museum Shop.
