Habitually Check Status of Resource Areas - Another big mistake that players tend to make is not keeping an eye on the areas that they have their farms and plantations on. Players should remember that almost every good can be converted into a higher quality product. These are great investments that the player will want to look into as soon as possible if they want to maximize the profits on everything that is produced. Tobacco can be turned into cigars using a Cigar Factory, sugar can be made into Rum using the Distillery, and even fish can be converted into a higher quality good using the Cannery. Instead, players can take those products and refine them into something more expensive.
This is because just selling raw products isn't a very good way to make money. Refine Products Before Selling Them - As the player begins to progress further in the game things will start becoming more expensive, and they will quickly realize that those farms and plantations just aren't cutting it the way that they used to. Additionally, the player can also spend a little bit of extra money to turn the college into a research institute as well which will allow it to function in the same way as the library. It may be an expensive option up front, but once this has been completed the player won't have to hire better workers from other countries. This allows the player to educate their citizens and enable them to take positions doing more complicated jobs. Educate Citizens to Cut Down Costs - To make up for the costs of those scientists, players will want to then build a college as soon as they are able as well.
