LOL i doubt you ( Brittany Vincent, the reviewer) have your centuries straight. from the review pics, and subject matter, it looks a lot more like 16th and 17th centuries in Spanish colonies. nobody in the 18th century colonized a new country in t he americas, ( except a little bit of western expansion in N america from existing colonies, and without all that style of garb and NO armor), ---by then armor and helmets were out of style in European cultures..
Everything looks like the two previous centuries i mentioned and nothing like the 18th century. Or did the game specify 18th? because it is off by one or two hundred years if they are claiming to hark back to a certain colonization time frame. Those characters are styled like Conquistadors, and that was before 1700.
