Honestly, this econimic/trading sim is just so much fun (plus it's so much more than just a trading sim if you dive deeper and learn all the underlying mechanics, like popularity, elections or military/mercenaries). I loved to play a quick, relaxing 15 turns game every once in a while, and now thanks to the GOG release it's so much easier. One oversight though - the GOG version comes with no manuals or documentation, which explains some of the aforementioned mechanics. Fortunately it's easy enough to find a PDF online.
