Increase Barracks cost from $300 -> $500

I've been trying to increase the diversity of available early-game build order choices. To do this, I've increased the cost of early-game buildings like Power Plant and Barracks, while increasing the power consumption of the Refinery. This forces players to make choices with more significant consequences. The cost (money=time spent building) of power and barracks are so low right now that the time you spend building them is totally inconsequential to the build order. This leaves very few options, and most people simply pick Barracks, Refinery, Refinery.

Giving some non-trivial time cost to Power and Barracks will allow people to have more possibilities for different openings.
