Sid Meier's CivNet

Sid Meier's CivNet takes the classic Civilization formula and adds something that can make even the most peaceful empire suddenly become dangerous: other human players. Released in 1995, it allows several players to compete over territory, technology, diplomacy, resources, and military power across a shared game. The familiar Civilization mechanics remain intact, but multiplayer changes the atmosphere considerably. A computer opponent may be predictable; your friend sitting across the room is much more likely to remember that you stole his favorite city three hours ago. CivNet encourages negotiation, alliances, betrayal, and long-term planning, making every session potentially different. Its graphics are firmly rooted in the early Windows era, but the strategic foundation remains compelling. It is essentially Civilization with added opportunities for arguments, suspicious diplomacy, and the occasional declaration of war over something that began as a perfectly reasonable trade.
