TradeWars 2002, also known as Trade Wars 2002 or TW2002, is a space game developed starting in 1984 and continuing through the 1990s by Gary Martin for play as a BBS door game, with later versions developed by John Pritchett both for BBS and, starting in 1998, a devoted game server called TWGS (Trade Wars Game Server). The player is a trader in a galaxy with a fixed set of other players (either human or computer). The players seek to gain control of a limited set and amount of resources (specifically fuel ore, organics, and equipment) and travel through sectors of the galaxy trading them for money or undervalued resources. Players use their wealth to upgrade their spaceship with better weapons and defenses and fight for control of planets and starbases.
