Zombiemane's review is spot on, and there's nothing I can add to his masterpiece review. I can only confirm that for the patient CRPG gamer this game is a must buy. I played it when it originally came out in 1992, and spent almost as much time playing it as I did Ultima VI and VII. It has a crowded, living world full of NPC's and a combat/stat system much like Realms of Arkania, difficult to get used to, but once you do you'll be restarting and enjoying every minute of it.
Along with Detroit this game kept me up many a late hours during high school and college. It has many customizable features including the need to balance salt in your food with the ice in your softdrinks. Research is included, and pathing plays a huge role. Most modern sims owe a great deal to this game and some are simply the same core game with different themes and upgraded graphics. If you want to see where it all began this is as good a place to start as any.
This is an automatic buy for most Origin/Roberts fans. For newer folks...This is basically an upgraded form of Privateer but on Earth. It has the same type of story trees, and missions. Ironically the story still holds up well in today's world.
