Ports of Call is a business/strategy game created by Rolf-Dieter Klein and Martin Ulrich in 1987 for the Amiga. The game was ported a few years later to MS-DOS.
This title is an absolute classic. For many, it represented the first game played on an Amiga since it was included in the Amiga500 Deluxe pack. Compared to the titles of the '90s, the graphics seem to be a bit rough but still very detailed and pleasant. The gameplay is brilliant and immersive, with several options and actions available for players to compete in "hot seat" mode. This made this game the best trading sim available on the Amiga then.
You start selecting your home port; then, you must purchase your ship and begin trading goods from one port to another to make enough money to grow your fleet and company. There are many similarities between this game and 1869 or The Patrician (other trading sims made in Germany).
The mini-games differentiate the game from other business simulations and add some diversions. Overall, it's a classic you must try, especially if you like the genre.
