This campaign presents us with three scenarios, each of which give you control over a conquistador army to destroy an opposing Aztec army. The game does not include much more than that. What stops the playability from being a 1 is that, firstly, it's playable, and secondly, it can potentially be somewhat remotely interesting when you try out different ways to reduce casualties. It is very hard to include flaws in this playability when the playability is close to non-existent, however, the author manages to not make the enemy "Immobile Units" thus making you search for an exploring unit across an empty plain of Grass 1. I'm sorry, but using the Marco Polo cheat is totally and utterly understandable.
Winning is a certainty. The army you are provided with is simply superior to the opposing Aztec army and if you want to lose you have to try very hard. As I mentioned before, the only thing the horrendous balance leaves you in terms of entertainment, however minimal, derives from trying to conserve as many units as possible in the battle.
There is nothing special in this campaign. Cities are either laid out much like the AI would lay them out in RM games, or buildings are placed in long, boring lines. Sadly, even these buildings are not overly suitable for mass production, since some sides are not exposed...
Map Design: 2
How to design a map of the type found in this scenario is to designate a patch in the minimap and then to crudely enclose it with trees or water. The reason I have not given it a 1 is because the author navigated his way into the Gaia "Other" Units section and scatter a few objects across the map.
The only story was history, which was not even mentioned in the file and the scenario simply does not have the content for me to evaluate its historical value. As for the instructions, they were non-existent.
