For those interested in games using the timer & score victory conditions. This simple mod is primarily designed for multiplayer games to be completed in a relatively short time; 1-3 hours for example. The Cost of Buildings/Maintenance has been halved to allow for more "active" play.
Update: Mega Farms & Hydrogenator set to zero (0) maintenance costs. Time to Build = 120, was 240. However there still is a cost, just depends on tile development. Max appears to be 90k, & min appears to be 10k. Setting the Tile Maintenance to zero (0) might be too strong. Should help in competing against the Mechs.
