What is this system

Traveller is the granddaddy of sci-fi tabletop RPGs (1977, Marc Miller). Current edition is Mongoose 2e: 2d6 + modifiers, skill checks, lifepath instead of classes. You don't build a hero — you build a biography: a stint in the Imperial Navy, a botched brokerage deal, a leg lost on a colonial backwater. The game is about freelancers on a beaten-up ship, a mortgage on the jump drive, and cargo you'd rather not inspect.

Setting

Charted Space and the Third Imperium. 11,000 inhabited worlds, jump drives up to 6 parsecs, feudal aristocracy with lasers. Beyond the sectors lie frontiers, pirates, lost colonies. You're not galactic saviors — you're a free trader's crew with a bank payment due every 30 days.

What it looks like at the table
Lifepath. You picked Scout. Enlistment roll: 2d6, need 6+. You're in. First term — four years of survey work. Survival roll: 1+1 = 2. Failure. You consult the Mishap table (d66): 11 — 'Severely injured, career ends.' In Mongoose 2e you usually survive, but the scars stick. The table laughs. You roll again — this time, Drifter. Forty minutes later you've got a grey-haired veteran with three terms, a cybernetic arm, an enemy captain, and a share in a Type-A Free Trader. The game hasn't started, but the biography already has.

Key mechanics

Lifepath, not level-up

Career before play: service, events, failures. You can die at chargen. But what walks out is a person with scars — not a walking stat block.

The ship is a character

Free Trader, Scout, Far Trader. A 40-year mortgage, fuel costs, insurance. The ship is your fifth crewmember and your biggest problem.

Trade as gameplay

Buy wheat on an agri-world, sell it on an industrial one. Broker rolls, speculative cargo, smuggling. A whole economic mini-game.

2d6 + everything

One roll for everything: skill + stat + modifier, target 8+. Simple curve, intuitive odds. No d20 required.

What people say
I think even its harshest critics would have to admit that the worldbuilding is incredible, if a bit spread out.— Aki, Cannibal Halfling Gaming
