Ooer, Dirk tries to enter a house of ill-repute - for the same price as a crew member it'd better be worth the cash

The port of Guangzhou, Dirk's adventure begins; shopping list at the ready, a boat, six crew, food, wine, women and song. Who said this was a bad life?

Dodgy dealings and opium smuggling on the streets of Guangzou in Ocean's adaptation of James Clavell's Tai-Pan

In the Year Of Our Lord 1841, the eastern seaways are teeming with traders. And in this game based on James Clavell's best-selling novel you are Dirk Struan, a merchant intent upon amassing a fortune as quickly as possible in the streets and seas of the Orient.

As in any trading game, a financial stake is required; in Tai-Pan it's to be found in the local town of Canton - a loan of $300,000, repayable in six months on pain of death. The sum is sufficient for some of your needs, but not all. For instance, you need a ship, and the three up for sale are a lorcha (a lightly armed, fast smuggling ship) at $150,000, a standard trading clipper with more cannon and crew for £250,000, and a heavily armed frigate which at $400,000 is out of your range - at first.

The stews of the Far East offer delights, dangers, deals and man-power. Once purchased a vessel must be crewed, either with mercenary sea-dogs or with infinitely cheaper press-ganged labour. The jobcentres for the latter are inns, where only the most exhausted and drunked seafront dregs are incapable of resisting their unceremonious enlistment.

With a full complement of crew (some ships need more sailors than others), the vessel can be loaded with such valuable objects as maps, compass, telescope and sextant, foodstuffs and trading goods bought from warehouses and suppliers.

During these consumer expeditions, you may find gambling dens where you can bet on a race betewen mythical beasts, substantially plumping your wallet or giving it anorexia. Other urban delights include a brothel and inn that can delight - and leave you tired, drunk, and susceptible to press-ganging.

In town, smugglers may accost you and try to sell you highly dangerous contraband, which is very profitable when traded between ports - but carries the risk of gaol.

With purchased itmes stored in your ship's limited cargo space, you choose a shipping route and set sail for distant ports. Weather conditions, wind direction and pirate ships can jeopordise any voyage, but a careful choice of route can diminish such problems.

As you put to sea, the street scenes are replaced by a bird's-eye view of ocean and land. Beneath this geographic scene are seven icons which raise and lower the ship's sails, assess the wind direction, provide a telescope, offer a combat mode, unfurl a map of the China Seas and feed the crew - important, because otherwise they might mutiny from hunger or succumb to scurvy, the sailor's disease caused by lack of vitamin C.

With a powerful frigate, you can turn privateer and plunder other craft. If hit by cannonballs a ship is disabled and can be boarded by sailing alongside and killing its Captain.

But fierce resistance can be expected, and you might have to retreat to your vessel. If too many of your crew are killed in battle, your own ship becomes unsailable. (Likewise, don't kill too many enemy sailors - you'll need them to sail the captured ship.) And fighting reduces your men's stamina, already eaten away by hunger.

Careful cannon fire ensures that the captured vessel and its cargo remain intact and seaworthy and will fetch a high price in port. But other privateers my attempt to take your captured ships and end your quest for fortune.

As you build up your fleet, a great trading empire can be founded, generating enough wealth to repay your debt and leave you a colonial master of the Orient.
