...each unit costs either one or two production points per turn depending upon your form of government,...

Government page says that each unit costs 1 production regardless of regime. Only food cost (for settlers) does varry.

buy a wonder Edit

I can not understand the last sentence in the formula on how much does it cost to buy a production

The cost is multiplied by two if the project is a wonder.

Can you clarify better? Does it mean that after the second formula (the one for buildings and non-unit) is applied, the result of this is doubled. Can this be even more clarified by separating the explanation in three section (one for units, one for everything else but wonder and one for wonder)? -- AnyFile 10:13, 19 March 2009 (UTC)
