I'm pretty sure that additional characters were once part of the plan. Remember that this game had a long development cycle and a lot of hiccups along the way. A lot of what was originally envisioned, or promised, was changed in scope in order to get the game out the door. Go read the archived previews in some of the online game sites for giggles. You'll understand why some of the fans were pretty let down with the final product's shallow nature. Recall that at one point, this game was actually slotted to become an MMORPG.
How about these select quotes:
"Your ship will automatically pilot itself, following nav points to complete missions or performing a variety of maneuvers in combat. Unlike traditional space games, which frequently play like a shooter in a 3D arena, Freelancer has a much more tactical feel. You simply click on the maneuver you want your ship to perform, target your enemy with your mouse cursor, and fire away. Freed of direct piloting chores, I found myself making strategic decisions in combat: Which enemy subsystem do I target, how is my power being managed, which weapons should I be using? It was much more engaging than the de rigueur furballs of even the best space games. And should you so desire, you can override the automatic pilot and steer yourself." - Gamers.com
"Just as in real life, if there is a gold field somewhere in the Freelancer universe, we have created a mining operation complete with mining ships, a base to process the ore, police patrols to protect the mine, paths for transport ships to bring the ore to the consumers, and criminal groups to attack these transports or the mining operation itself. The inherent tension between miners and criminals creates a threat level for the gold commodity in this area, which, just as in real life, dictates the price." - Gamespy interview with DA
"The economy can be affected by outside influences. A band of pirates could rob a grain-producing planet of thousands of pounds of grain. This would automatically spawn some missions to either retrieve grain, or kill some pirates to get them off the planets back." - Gamer Web
"Players will have a while to wait before they can find out—Freelancer is currently scheduled to be released in the winter of 2000." - Chips & Bits
"As a space-sim, you will get to blow up spaceships. The cut scenes include shootings and killing people. There are many uses of the “D” word and “H” word, and a use of “S.O.B”, not abbreviated. There are also small sexual innuendos in one cut scene. One regarding Trent (the main character) arriving on the planet with two women. In addition, there is bribery involved at times. Someone may offer to change your stance with particular factions…for a price. The use of alcohol and cigarettes is also depicted." - Christian Computer Games Review
Okay, those last two were just for giggles.
