One of Interplay's very first games is a fine entry in the text/graphics adventure realm. You, the titular Tracer, are an intergalactic superspy on the trail of a rabble-rouser called "The Wing." Your employers, the SIA, are eager to have you haul him back to base, but not so eager that they give you a big budget—the early part of the adventure is spent as much on finding ways to raise money ("sols") to buy fuel and travel about the populated planets of the galaxy than it is actively seeking the Wing. Contacts and informants on most worlds give you hints to drive you onward, so there are few instances where you genuinely must guess what the next destination should be.
As an interplanetary secret agent, you must roam the galaxy in your extremely fuel-conscious space ship (only 500 gallons to the nearest planet). Heaven knows what sort of engine your ship possesses, but as stars scroll past your cockpit you can hear what sounds like a very unhealthy motor-scooter in the background.
There are some touches of dry humour, including an interminable queue of people that you can stand in for ever, never quite reaching the end. You'll also have some trouble with a certain crazed dwarf and some unstable stalactites -- at least if you go the way I did. A 'living tutorial' helps new adventurers get into the swing of things.
