If you have a player whose really likes to create the character they've envisoned in their head, then Traveller might not be their game. Even the type of planet you grew up on is rolled randomly. You can try to push your character down a certain path in regards to education and career, but at any time one die roll can radically alter your character's trajectory. I haven't played yet, but made several characters just to get the hang of it and got some wild results.
- I ended up with a psychic.
- I tried to push a character into engineering, and was somewhat successful, but he ended up with a 3 in the melee (knife) skill and a 4 in Steward. In this context, a steward attends to the needs of passengers on the ship. With a 4, my character was a space butler on par with Jarvis or Alfred.
- I ended up with a convict in his 70s by the time I rolled to get out of prison.
- A high ranking retired military officer with his own scout ship. I just kept rolling promotion after promotion.
