Better Bridges

Contains a variety of gameplay improvements to the Ancient, Medieval and Modern Bridge buildings available throughout the ages: Bridges can be built in towns Bridges continue to function as bridges in the next age Bridges remain buildable until the next bridge type is unlocked (but at the increased cost of the current age's bridge) Bridges upgrade automatically to the next type once unlocked Medieval and Modern Bridges have a Gold adjacency yield from quarters (lost on age transition just like other building adjacencies) Overall, these changes should make it easier to use bridges for their intended function. The economic upgrade allows the tile to compete for total adjacency yield (i.e. specialist yields) with other two-building tiles. To-Do's and other issues: In the long-term, I want bridges to use their own building slot, similar to walls. This can be done on the gameplay side but if the bridge ends up in a district with two other regular buildings, one of them will not display its model, so I'm waiting with this change until we have official mod tools and can mod art defines. The UI is missing references to some possible adjacency types, including those from quarters. There might be some cases where the new adjacency bonus does not show properly, but in the build menu and on when placing the bridge on the map, the total yields are calculated correctly. Any bridge will be instantly finished if under construction right when a new bridge type is unlocked. It's up to you if y
