Buildings

Buildings are another income source similar to Dinosaurs. As such, both income sources have some fundamental properties. Both have a income amount and a time period and these two properties determine the rate at which coins are accrued by the building/dinosaur. When the income is reached, coins are no longer added. Both buildings and dinosaurs receive bonuses from Decorations that increase the income they accrue (and since the time period does not change, this also increases the accrual rate). Also like dinosaurs, buildings take time to build.

Buildings do have a few differences from dinosaurs. For one, dinosaurs can be fed to increase their level, which increases their base income rate while buildings cannot be upgraded. On the positive side, you may have multiple buildings of a given type, but only one dinosaur of each type.
