Palm OS 3.1

Pocket Civ is a civ-like game for Palm OS, having some degree of playability, but lacking many of the elements of the PC game. The ultimate goal of creating a game similar to Sid Meier's original Civilization (Civ 1) is more of an abstract destination; it's the journey that counts.

Updated Description:

v1.5 (Oct 8, 08):
Features: Irrigation and Mining. Settlers can be automated by tapping 'A'. Automated Settlers improve terrain near your cities, but never found a new city.
Trade Routes and Rates. Use Caravans to establish trade routes. Trade is also earned by workers on terrain surrounding the city. Trade is then split into gold and science. Use the Game/Trade Rates menu to change the allocation.
Changes to Gold. If there is not enough gold to pay for the upkeep of city improvements, citizens will react by permanently closing them down. One random city improvement is destroyed in every city until the budget balances.
Buy and Sell. Buy whatever the city is building to complete it in one turn. Sell city improvements. One may be sold per turn in every city.
Resource Usage. Units now require resources for maintenance. Shields and food may get used up by supported units. Check resource usage by tapping 'Res' on the city screen. Units are maintained by their home city. Change it using the Orders menu.
